Abstract

Research on recovery of Cu (II) and Cr (VI) from electroplating liquid waste has been carried out using a Polymer Inclusion Membrane (PIM). PIM has a high stability to overcome the weakness of liquid membrane instability. The PIM membrane was placed between two phases namely the feed phase as a metal source of Cu (II) from electroplating waste with pH 3 and the receiving phase which is HNO3 solution with pH 1 and pH 4.4 in the feed phase and pH 6.3 in the receiving phase with NaCl 2 N for metal Cr (VI). Recovery efficiency is known by determining the concentration of Cu (II) and Cr (VI) in the feed and receiving phases using AAS, while the membrane characterization were carried out using FTIR, SEM and UV-vis spectroscopy. The resulting PIM membrane has properties of thin, clear and flexible. AAS data showed that the percentage of PIM transport with stirring for 24 hours performed the highest percentage of Cu (II) metal transport from feed phase of 83.41% and transport in the receiving phase of 72.56%. While the percentage of optimum Cr (VI) transport was 97.8% in the feed phase and 76.5% in the receiving phase. The results of membrane characterization using FTIR and UV spectroscopy showed that the PIM membrane was quite stable. While the results of SEM show that there were no pores in the membrane so that the transport occurs by diffusion through the intermediate of the carrier compound. Keywords: electroplating waste; liquid membrane; PIM

Abstract

A computational approach to assess the emperical results of eugenol affinity, eugenoxy acetate (EOA), and pyridine methyl eugenoxy acetate (PMEOA) against Cu2+has been done. This research aims to determine the effects of the functional groups (−OH, −COOH, and −N) on eugenol and their derivatives on the selectivity of Cu2+adsorption experimentally and to calculate the energy interaction between eugenol compounds and derivatives with Cu2+. The experimental approach was carried out by solvent extraction method, using 10 mL of Cu2+10 ppm solution along with 0.3089 mmol of eugenol, EOA and PMEOA. The remaining concentration of Cu2+metal after extraction in the water phase was measured using an Atomic Absorption Spectrophotometer (AAS). Assessments of the Cu2+metal interaction with eugenol, EOA and PMEOA compounds were carried out using the ab initio method with 6-31G** basis set to predict the interaction energy. The results showed that pyridine methyl eugenoxy acetate (PMEOA) can separate Cu2+better than eugenol and EOA with extraction efficiency (% E) = 78.76%. The calculation results of Cu2+metal interactions with eugenol, EOA, and PMEOA compounds found that PMEOA has the lowest energy of interaction compared to eugenol and EOA with Cu2+metal.

Abstract

Research of chromium (VI) separation has been done using polymer inclusion membrane (PIM) method. This study aims to generate PIM, separate the metal ion chromium (VI) using PIM and determine the effect of the concentration of the feed phase, the thickness of the membrane and the amount of usage of the membrane for ion chromium (VI) diffusion.Polymer inclusion membrane (PIM) was made by mixing Aliquat 336-TBP as carrier compounds, PVC as the base polymer, DBE as a plasticizer and THF as a solvent. PIM membrane was placed between the source of analyte as a feed phase and result of the separation as a receiver phase. Feed phase was electroplating waste metal containing chromium (VI) at pH 4, while the receiver phase was a 2 N NaCl solution with a pH 6.7. The change of variables in this study were the concentration of the feed phase at various dilution i.e., 100x, 50x and 10x, the thickness of the membrane i.e., 25 μm, 20 μm and 10 μm, and the time of membrane using i.e., 1, 2 and 3 times. The concentration of chromium (VI) diffused after separation process was analyzed by atomic absorption spectroscopy (AAS). The stability of membrane was observed by analyzing the presence of membrane’s component in the feed phase and in the receiver phase. The analysis was conducted by UV-Vis spectrophotometry. Meanwhile, scanning electron microscopy (SEM) analysis was used to determine the morphology of membrane surface.The results showed that the chromium ion concentration diffused from the feed phase was 99.24%, meanwhile the 85.88% of it diffused to the receiving phase. The highest Cr(VI) ions diffusion was occured at the first use of PIM membrane with a thickness of 10 μm and the concentration of the feed phase was 10.55 ppm (resulted from 100 times dilution). Therefore, it can be concluded that the diffusion of chromium (VI) ion was influenced by the concentration of feed phase, the thickness of membrane and the number of membrane application.

Abstract

Sintesis Ionic Imprinted Polymer (IIP) dilakukan dengan variasi penambahan crosslinker PEGDE (Polyethylene glycol diglycidilether) yang kemudian diuji selektivitas IIP terhadap ion logam Fe melalui proses adsorpsi. IIP merupakan metode mencetak ion logam yang terikat dalam polimer, selanjutnya dilepaskan dari matriks polimer menghasilkan cetakan yang sesuai terhadap ion target. Tujuan penelitian ini untuk menghasilkan IIP dan NIP dari polieugenol dengan variasi penambahan crosslinker PEGDE perbandingan sebanyak  1, 2 dan 3 mol, mengetahui pengaruh jumlah mol crosslinker terhadap selektivitas adsorpsi IIP yang melibatkan rongga imprint/cetakan, serta mengetahui pengaruh logam kompetitor terhadap selektivitas adsorpsi IIP terhadap logam Fe. Selektivitas adsorpsi ion logam Fe(III) dengan penambahan crosslinker PEDGE 3 mol lebih besar dibandingkan dengan penambahan crosslinker PEGDE 1 dan 2 mol. Selektivitas adsorpsi Fe lebih besar pada Fe-Cr dibandingkan dengan Fe-Cd dan Fe-Pb.Influence of Crosslinker Mole Amount on the Selectivity IIP-Based Polyeugenol Towards Fe(III). The synthesis of IIP (Ionic Imprinted Polymer) was carried out using PEGDE (Polyethylene glycol diglycidilether) crosslinker addition in various moles which was then tested for IIP selectivity for Fe metal ions through the adsorption process. IIP is a method of metal ions printing which are bound in a polymer, then released from the polymer matrix to produce a suitable mold for the target ion. The purposes of this study were to produce IIP and non imprinted polymer (NIP) from polyeugenol with the addition of various moles of PEGDE crosslinkers as much as 1, 2 and 3 moles, and to determine the effect of the number of mole crosslinkers on the selectivity of IIP adsorption involving imprint/mold cavities, and the effect of competitor metals on IIP adsorption selectivity towards Fe metal. The selectivity of Fe (III) metal ion adsorption with the addition of 3 mole PEDGE crosslinkers was greater than the addition of 1 and 2 moles PEGDE crosslinkers. The selectivity of Fe adsorption is was greater in Fe-Cr compared to Fe-Cd and Fe-Pb.

Abstract

Fe-Ionic Imprinted Polymer (IIP) from polyeugenol as base polymer and polyethylene glycol diglycidyl ether (PEGDE) as cross-linking agent had been synthesized to adsorb Fe(III) from aqueous media. The non-imprinting material (NIP) and polyeugenol were used in the adsorption study as control. Synthesis work included polymerization, template uploading, crosslinking and template removal, optimized for different template ion upload pH and concentrations. The polymers were characterized by FTIR spectroscopy, XRD and SEM-EDX, followed by adsorption test to study the adsorption kinetics and isotherms for all adsorbents. Selective adsorption study of IIP was carried out using binary mixtures of Fe(III) and Cr(III), Pb(II), Cd(II). Experimental results showed that the optimum conditions for the synthesis was template upload pH of 3, Fe/polyeugenol ratio of 1 mg/g, while the optimum adsorption pH was 3. The adsorption mechanism of Fe(III) on all adsorbents was dominated by hydrogen bond formation. The adsorption kinetics followed the pseudo-second-order model while the equilibrium data was best explained by the Langmuir isotherm model. The adsorption capacity of Fe(III) on the IIP was 12.73 mg/g, higher than that of the other adsorbents. Results also show that IIP-Fe was more selective toward Fe than NIP by 2.69 (Cd), 1.66 (Cr) and 1.6 (Pb) fold, respectively.

Abstract

Research into the synthesis and use of a novel carrier compound, thiazoethyl methyl eugenoxyacetic acid (TMEAA) for selective transport of Cu(II), Cd(II) and Cr(III) metal ions in the bulk liquid membrane (BLM) technique was conducted. TMEAA was synthesized from eugenol. Eugenol was acidified into eugenoxyacetic acid and subsequently esterified using 4-methyl-5-thiazoethanol. Analysis of the result was performed using GC-MS and FTIR. The TMEAA obtained was liquid, viscous, blackish-brown and fragrant, with a yield of 88%. This compound was soluble in benzene and chloroform but insoluble in methanol. The GC-MS analysis result showed the presence of a single peak, with a retention time of 26.5 min and an area of 100%, while the disappearance of vibration mode at 1727 cm-1 was attributed to acid absorption and the FTIR spectrum indicated that formation of an ester group had occurred. TMEAA was used as a carrier compound in the BLM technique to transport Cu(II), Cd(II) and Cr(III), using chloroform as a solvent. The results showed that TMEAA was more selective for Cu(II) and Cd(II) than Cr(III). Moreover, the research proved that N and S groups of TMEAA were selective for Cu (II) and Cd (II).

Abstract

In this research, Polyeugenoxy Acetyl Tiophen Methanolate (PEATM)-Au ionic imprinted membrane (IIM) was synthesized. IIM is a PEATM based membrane that has Au(III) ion molds. The PEATM synthesis was analyzed using FTIR spectroscopy, and its relative molecular weight was determined by the viscometry method. To find out the presence of Au(III) templates on IIM, FTIR spectroscopy and SEM-EDX were used. The results of FTIR spectroscopy & SEM-EDX analysis prove the existence of Au(III) metal ion templates at IIM. Through FTIR spectra, it could be seen that the absorption area of the -OH group was widening. In the IIM, the CS group wave number (702.9 cm–1) also shifted to a larger wavenumber (848.68 cm–1), this is likely due to the presence of PEGDE as a crosslinker agent and PVA as a plasticizer on the membrane that interacts with PEATM-Au, which influences the shift of vibrational wavenumber of CS bonds. It was also found that the most effective pH of the feed phase for the transport was at pH 3, and the most optimum transport time was 24 h for IIM and 48 h for NIM. The transport of Au in binary mixture of Au/Cd, Au/Fe, and Au/Pb also proves that the presence of Au(III) ions in IIM makes IIM more selective to Au(III) metal ions than NIM when used for the transport process as it transports Au more than the other metals. These results were as expected by using the HSAB theory as its groundwork.

Abstract

Diabetes mellitus is a chronic disease in which the body is unable to metabolize carbohydrates, fats, and proteins. In this study, eugenol was polymerized and then contacted with glucose and crosslinked using polyethylene glycol diglycidyl ether (PEGDE). The resulted PE-Glucose-PEGDE was eluted using ethanol to form MIP-Glucose. It was then characterized by FTIR, SEM, electrodes using the Eutech 510 potentiostat and UV-Vis spectrophotometer. The result of polyeugenol synthesis is a reddish-brown powder with a yield of 99.90% and a molecular weight of 6318.033 g/mol. UV-Vis spectrophotometer analysis showed that the contacted glucose was 2152.505 ppm. SEM results showed differences in the surface morphology of the material, indicating the formation of cavities in MIP and ESM, while no cavities are found in NIP and ESN. The electrode optimization resulted in the best composition ratio of MIP 1 mol: paraffin: graphite, respectively of 20:35:45. The resulting electrode has a Nernst factor of 20.24 mV/decade with a measurement range of 10–5–10–1 M, a limit of detection value of 8.363 × 10–5 M, and the value of the selectivity coefficient (Kij) of the electrodes in a (10–5–10–1) M fructose solution was 0.3733; 0.23048; 0.17864; 0.12359; 0.1073.

Abstract

Polymer inclusion membrane (PIM) has recently evolved as an alternative separation technique to conventional solvent extraction as it eliminates the use of toxic solvents, reduces separation cost, and simplifies the separation process. PIM is the new generation of a liquid membrane made by casting solution containing liquid phases (extractant and plasticizer/modifier) and base polymers. Despite its better performance and stability in comparison to the previous types of liquid membranes, PIM's robustness for applications on an industrial scale is still considered insufficient mainly due to its limited stability in the long-term separation process. In recent years, different approaches have been devoted to improving the stability of PIM while maintaining its performance. This review aims to summarize and evaluate the current literature on the improvement of the performance of PIMs with particular focus on the use of alternative base polymers, including non-conventional linear homopolymers, copolymers, or cross-linking polymers. Furthermore, more emphasis is given to the composition, fabrication process, and application of the PIMs. Finally, the performance of the PIMs with the alternative base polymers in terms of extraction rate and long-term stability is presented and compared to the PIMs fabricated using their corresponding common base polymers.
