Removal of Heavy Metal Ions with Hacac-Silica

Abstract:

This paper presents a new decoration view functionalization of mesoporous silica to extend their applications to heavy metal ion removal. The study showed that Hacac can be incorporated into the structure through in-situ strategy, and the calcined Hacac-silica possesses advantages of high specific surface area of about 1496 m²/g and pore size of 4nm, ordered spheric morphology of about 300nm in diameter. Auxiliary by ultrasonic technology, the heavy metal ions remove rates are more than 95% for Pb²⁺, Cu²⁺ and Cr³⁺. More choice of chelating agents can be used for further functionalization of silica based mesoporous material.
