Abstract

Commonly available methods for the removal uranium from an aqueous solution include sorbtion using pillared clay as adsorbent. This research about sorption of uranium from aquous solution with pillared clay and choosing best waste loading for immobilization pillared clay containing uranium by using epoxy resin polymer. Uranium used is simulation waste made from uranyl nitrat hexahidrat with 50 ppm in concentration. Pillared clay was made by reacting between na-bentonite and zirconyl chloride (ZrOCl2.8H2O). The research was carried out by varying influent factors to the adsorption process, variable of Zr as pillar material, contact time, and pH. Choosed variable would used to make pillared clay containing uranium which would be immobilized by using epoxy resin polymer and varying waste loading. Optimum condition of uranium adsorption was obtained at Zr concentration of 0,01M, pH 7, contact time 16 in minutes with removal uranium 42.6%. Base on density, compressive strength, and leaching rate the best block polymer-waste was waste loading 20%. On this condition, the density of polymer-waste block was 0,9938gram/cm3, compressive strength was 20, 179kN/cm and was no detection for leaching rate. Key word : pillared clay, immobilization using epoxy resin polymer, waste loading, adsorbtion
