The present work proposes to examine chemical characteristics and behavior of two bifunctionalized silicas exhibiting either a mesostructure (i.e., MCM-41) or not (i.e., silica gel, denoted here SiO2) with respect to the immobilization of chromium species. The organo-functional groups selected to achieve this goal are mercaptopropyl and propylsulfonic acid moieties (MCM-SH,SO3H), on one hand, and mercaptopropyl and ethylenediaminetriacetate groups (SiO2-SH/ED3A) on the other hand. The research has been started with structurally ordered materials, of MCM-41 type, to ensure high surface area and easy and fast accessibility to the functional groups. On the basis of thiol-modified MCM-41, a set of sorbent samples containing different ratio of g...
