Abstract
Organomineral sorbents were prepared by sorption immobilization of Xylenol Orange on the surface of two different samples of silica gel from aqueous solutions with pH 1.68 under static conditions. The diffusion coefficients of Xylenol Organe in the near-surface layer of silica gel and the equilibrium sorption constants were determined. Wash-out of the dye from the sorbent was studied. Sorption of Cu(II), Zn(II), and Pb(II) on the sorbents from aqueous solutions with pH 5.8 was studied.
