ABSTRACT:
A method of treating silica in an aqueous environment includes dispersing silica particulates in an aqueous environment to form an aqueous dispersion, reversing a net charge of a surface of the silica particulates from negative to positive using an inorganic treating agent to form surface-activated silica particulates, and contacting the surface-activated silica particulates with monoaminoorganosilane reagents to form reagent-modified and surface-activated silica particulates.
