Abstract
Sorption properties of clinoptilolite tuff modified by Fe-containing s olutions were studied. The absence of sorption of monocharged anions a t any pH of the solution and a high sorption capacity (up to 2.0 to 2. 5 mg-eq g(-1)) for phosphate ions at pH 10 to 11.5 were shown. Desorpt ion of phosphates by solutions of salts and mineral acids was studied.
