In this work mesoporous silica (MS) material was synthesized using block-co-polymer and used as an adsorbent support for arsenic removal. To meet this requirement, mesoporous silica (MS) with a large surface area (262.13 m 2/g) and uniform pore size (about 42Å) was prepared. This study showed that MS with a wide surface area, uniform pore size, and interlinked pore system can be synthesized at very low block-co-polymer concentration (1.0mM) and can be used as an efficient adsorbent support for the removal of arsenic. The post synthesis modification of MS support was done by doping with different amount of iron precursor to study the arsenic removal efficiency. The results show that the MS impregnated with 20% by weight of iron precursor have higher arsenic removal efficiency and better arsenic removal kinetics. The maximum removal was observed at slight acidic pH value of 6.0.
