【 摘 要 】

Mesoporous silica SBA-15 was synthesized using Pluronic 123 triblock copolymers as surfactant and functionalized with CPTMS to modify its surface. The synthesis of SBA-15 was prepared at optimized concentration of Pluronic 123 surfactant at 60 mM and showed surface area of 831.996 m2/g determined by BET N2adsorption isotherm test at 77 K. The functionalized product, CPTMS-SBA-15 on the other hand has lower surface area at 711.061 m2/g. This very high surface of CPTMS-SBA-15 and pure SBA-15 were used as adsorbent of Cd from industrial waste water using laboratory water samples. CPTMS-SBA-15 showed lower surface and pore size in comparison with pure SBA-15 but the effectiveness in adsorption of Cd was found higher than pure SBA-15. In this study, we compared the percentage of Cd removal using CPTMS-SBA-15 and pure SBA-15 systems. The materials were characterized by XRD, the presence of organic group was demonstrated by FTIR, and the ions concentration in solution after adsorption process was determined by AAS.
