Mesoporous silica SBA-15 has been synthesized using Tetraorthosilicate as precursor and Pluronic 123 triblock copolymers as template through the sol gel method. The surface of SBA-15 was modified using functionalization agent CPTMS (3-chloropropyl(trimethoxy)silane). SBA-15 was found to have surface area of 831.996 m2/g higher than CPTMS-SBA-15 which has surface area at 711.061 m2/g. Laboratory water sampels of Zn and Cd were adsorbed by CPTMS-SBA-15 and SBA-15. The comparison of SBA-15 and CPTMS-SBA-15 indicated that CPTMS-SBA-15 has lower surface and pore size. CPTMS-SBA-15 also has lower effectiveness in adsorption than SBA-15. The comparison between Zn and Cd percentage removal has been studied in this paper. XRD was used for identify the materials. FTIR was used to study the organic group of both SBA-15. AAS was used for determine the adsorption capability of SBA-15.
