Abstract

Studied the characteristics of natural zeolite catalysts activated and modifications and catalytic activity in the isomerization of glucose. Natural zeolite was activated by NH4NO3 2 M obtained catalyst HZA. While modification using 0,24 M Sn metal impregnated on HZA obtained catalyst Sn-HZA. At this stage, hydrothermal process carried out at temperature of 90 °C for 12 hours followed by calcination at temperature of 500 °C for 4 hours. The characterization includes the XRD analysis, SEM-EDAX analysis, acidity by ammonia method, and surface area by adsorption of methylene blue method. Glucose conversion was obtained through analysis of polarimeter at hour-0, 1, 2, 3, and 4 with temperature variation of 110, 120, and 130 °C. Solution which had the highest conversion resulted by polarimeter was analyzed by HPLC. XRD analysis showed that there were no changes in the structure of zeolite after activation and modification process. SEM-EDAX analysis showed that morphology of the zeolite surface is not damaged and Sn metal was successfully impregnated 6,94 %.

Abstract

Mesoporous NaX zeolite has been synthesized from calcined kaolin with the addition of 5M NaOH and CTABr surfactant as mesoporous template by hydrothermal method. The result of synthesis was used as anticancer loading agent of ethanol extract soursop leaves. Characteristics of zeolite were studied by XRD, IR spestroscopy, Nitrogen Adsorption and SEManalysis. The mesoporous NaX zeolite has been formed with mixing of A, Y, kaolinite and quartz phases. The surface of zeolite particles has changed from amorphous to regular and uniform particles. The pores of NaX zeolite belongs to mesoporous type with size 6.13 nm. Loading process of soursop leaves extract on zeolite decreased intensity and crystallinity of zeolite peaks. The new absorption in soursop leaves extract loaded on zeolite spectra was detected at 2928.174 cm-1. The surface of zeolite seen to be compact and irregular.

Abstract

TiO2 Anatase activities should be increased from the UV to the visible light photocatalytic activity of TiO2 to increase anatas. One efforts to optimize TiO2 anatase activity is doping by using dopant vanadium(V). Synthesis method which is used in this research is a solid reaction method.

Dopant concentrations of vanadium(V) which are used in the research was 0.3%, 0.5% and 0.7%. and the characterization used is X-ray diffraction and UV-Vis Diffuse Reflectance Spectroscopy. The result shows that there are a changing of particle size, band gap energy, and absorption of TiO2 anatas wavelength because of dopan vanadium(V) addition. While TiO2’s structure does not change. The crystal sizes of each TiO2 without doping, V-TiO2 0,3%, 0,5% and 0,7% are 53.21 nm, 47.67 nm, 79.65 nm dan 68.99 nm.  Band gap energy of each TiO2 without doping, V-TiO2 0,3%, 0,5% dan 0,7% are 3.309 eV, 3.279 eV, 3.270 eV and 3.259 eV.

Abstract

Effort that can  maximize the working of natural zeolite is by activation and modification as a carrier of active metals or commonly called impregnation. Modified zeolite by impregnation using titanium metal is to increase the performance of a pure metal catalysts such as low in thermal stability, decreasing surface area and sintering occurs (clotting) and expensive in the application. Bearers Treatment in the metallic solids by  impregnating the zeolite would make the metals in zeolites as bifungsional catalysts.Modified Malang’s natural zeolite starting with the activation process using a solution of NH4NO3 2 M, continued by the addition of titanium metal used in zeolite TiO2 solution with a concentration of 0.1, 0.2, and 0.3 M. Modified zeolite crystallinity characterized analized by XRD analysis. Methylen blue adsorption on Ti-zeolite is to measure the specific surface area. SEM surface morphology analysis is used to determine the content of the element is by using XRF analysis.Characterization using XRD analysis results indicate that Malang’s natural zeolite not changed in the structure, but it changes the intensity due to the addition of titanium. The largest surface area measurement obtained from the treatment of Ti-zeolite 0.1, 0.2 and 0.3 M are : 23.159; 23.077 and 20.848 m2/gr. SEM analysis showed that titanium metal dispersion fairly evenly after the modification. While from the XRF analysis showed that the ratio of Si / Al increased to 4.354 and content of titanium in the Ti-natural zeolite Malang is 13.6%.

Abstract

Removal methylene blue from water using coconut waste ash activated by NaCl is studied in this paper. The characteristic of morphology and pore structure of coconut waste ash is analyzed using SEM, show that pores were formed after activation. XRF analysis revealed that the coconut waste ash before activation contains 20,19 % of Si. The effect of NaCl concentration on the adsorption behavior is investigated. The results show that the optimum concentration of NaCl to activating the coconut waste ash is 300 ppm. The adsorption capacity of coconut waste ash without activation, NaCl-activated coconut waste ash on 200 ppm, 300 ppm, and 400 ppm is 1.103 mg/g, 1.152 mg/g, 1.2102 mg/g, and 1.1109 mg/g respectively.
