Study and Fabrication of Acid-Modified Diatomite

Abstract:

This paper presents an investigation of the purification and activation of a raw diatomite by acid treatment. In the acid modification process, the SiO₂ gel powder was adsorbed partially into the pure diatomite, blocking macropores and large mesopores of diatomite, which resulted in great increase of the specific surface area and SiO₂ content of diatomite. Thus, the as-prepared diatomite has potential use in the fabrication of catalyst carrier.
