Molecularly imprinted polymer is a polymer that synthesized together with targeted molecule (analyte) through polymerization process. When the polymerization has completed, extraction is taken to pull the analyte out of the polymer, and it will give a specific “frame” of targeted molecule which leave cavities and further is used to give specific recognition of the analyte. Functional monomer, template molecule, crosslinker agent, porogenic solvent and initiator are the main components involved in the synthesis of this kind of polymer. The right functional monomer is needed to make polymer building block with high selectivity when used as sorbent. The selection of suitable and precise functional monomer has been elaborated in this study. methacrylate acid, itaconic acid and acrylamide is then studies as functional monomer that will be chosen to give the best polymer performance as sorbent. From IR spectrum results, it can be concluded that polymer has been synthesized successfully. Peak at 1157 cm-1 which is a peak of C-N bond from β-lactam ring support this statement. Finally, it can be concluded that methacrylate acid is the best functional monomer for making polymer as sorbent for meropenem

The main objective of this study is to investigate the isotherm sorption of humic acid (HA) from aqueous solution onto dual nanofiber PMMA/PVDF. Batch adsorption experiments were carried out using HA solution as an adsorbate under variety of concentration in the range of 50-200 mg/L. The experimental data were analyzed by the Langmuir, Freundlich and Sips models of adsorption. The experimental results indicate that, the adsorption capacity of HA adsorption increases with an increase in the HA concentrations. The adsorption of HA onto dual nanofiber PMMA/PVDF agrees well with the Langmuir isotherm models with the maximum adsorption capacity was found to be 137.40 mg g-1 at concentration of 100 mg L-1.

Amoxicillin is one of β-lactam antibiotic in penicillin groups which their presence in surface water and wastewater not only affects water quality but also causes long-term adverse effects on ecosystems and human health due to their resistance to natural biodegradation. The processing of organic waste electrochemically has the advantage of cheap and efficient cost, exhaust gas that does not contain toxic and hazardous materials. We have studied the process of amoxicillin electro-oxidation mediated by a cobalt (III) ion called an electrochemical oxidation process mediated (MEO) in a voltammetry study using a platinum working electrode, Pt/Co(OH)2 and Pt/Co in various supporting electrolytes such as KNO3, NaClO4, Na2SO4 and phosphate buffer solution with concentrations 0.10 M. The results show that the amoxicillin oxidation peaks using the above-mentioned working electrode in various electrolyte solutions are in the potential range of 500-670 mV (Ag/AgCl). The presence of cobalt ions forming complex compounds with amoxicillin causes the oxidation current decreasing that indicates the presence of degradation to amoxicillin.
