Abstract

Laboratory wastewater in PT. Indo Sea Food is a type of waste generated from various laboratory activities consisting of the results or residue of chemical reactions, effects of washing equipment, and consumables from actions that have taken place. The use of chemicals during the activities carried out in the laboratory produces waste containing heavy metals, including the compounds FeCl3 and FeSO4. Oxidized Fe heavy metal waste usually has a red-orange color. It will be hazardous if the waste is directly discharged into the environment and disrupts the ecosystem because of its corrosive nature. Membrane technology is one of the current laboratory waste treatment methods that are efficient, cheap, economical, and accessible. The incorporation of TiO2 into the PSf membrane is expected to increase its hydrophilicity and macro-cavity structure. The purpose of this study was to find out how to make PSF membranes and PSF-TiO2 membranes, to know the characteristics of the membranes and to evaluate the performance of PSF-TiO2 membranes for the separation of Fe2+ metal from PT. Indo Sea Food Rembang. The PSf-TiO2 membrane synthesis begins by preparing a dope solution consisting of PSf as the primary polymer with a composition of 20%. The dope solution was then mixed with 80% N-methyl-2-pyrrolidone (NMP). The membrane was printed using the phase inversion method. The addition of TiO2 was carried out with three different compositions, namely 0.5wt%, 1wt% and 1.5wt%, which aims to determine the optimum condition of the membrane from various variations. The effect of the addition of TiO2 on the performance of the membrane can increase the flux and % of membrane rejection in the composition of the expansion of 0.5wt% TiO2 (PSF-TiO2 0.5wt%).
