Fabrication and Characterization of PSf/GO-SiO2 Membranes as Filtration of Detergent Contaminated Water

Abstract

Abstract The increasing use of detergents in daily life can cause environmental pollution. So, to solve the problem, membrane technology is suitable to reduce various pollution from water. Graphene Oxide (GO) and SiO2 are very much of concern and have been studied in recent years because they can change many characteristics of materials and can expand the range of applications in membrane manufacturing. So, this study aims to analyze the results of PSf/GO-SiO2 membrane fabrication by phase inversion method and analyze the results of PSf/GO-SiO2 membrane performance as detergent polluted water filtration. In GO synthesis using Hummer’s method, GO-SiO2 composite synthesis using Tetraethylorthosilicate (TEOS) in-situ hydrolysis method, and PSf/GO-SiO2 membrane fabrication using the phase inversion method. So, it is concluded that the PSf/GO-SiO2 membrane fabrication has been successfully carried out, as indicated by the SEM results; with the increasing presence of SiO2, the membrane pore size is getting bigger. For the performance of the PSf/GO-SiO2 membrane with UV-Vis test, the results showed that the flux value of the PSf; PSf/GO and PSf/GO-SiO2 (0.6) membranes was 119.58 L/m2.h; 140.35 L/m2.h and 157.79 L/m2.h respectively. In line with the results of the membrane rejection values are 95.22%, 97.68%, and 98.55%, respectively. The membrane with the best performance in the filtration of detergent-polluted water is the PSf/GO-SiO2 (0.6) membrane. The presence of SiO2 in the membrane causes a higher flux value because the larger membrane pore size influences it, so the PSf/GO-SiO2 membrane can be used to filtrate detergent-contaminated water.
