| Mesoporous silica material, MCM-41, has found several applications in the field of catalysis, separation technology and ion exchange. Having the appropriate features, such as large surface area and pore size, MCM-41 can be tailored to selectively remove contaminants in water. Thiol functionalities on the MCM-41 surface have already been successfully used in the removal of heavy metals in industrial runoffs. This poster explores expanding the application of these materials to the removal of arsenic and selenium in water. Naturally occurring arsenic and selenium in high concentrations in water pose health threats in various parts of the world. Common species include arsenate (As V), arsenite (As III), selenate (Se VI) and selenite (Se IV) in water. Different types of thiol-functionalized MCM-41, such as monothiol and dithiocarbamate, have been examined.
