ABSTRACT
We investigated the removal of As(III) and Cr(III) on the zeolite modified with manganese oxides. The results of our research show that zeolite behaves as a heterogeneous catalyst and removal of investigated elements occurs due to their oxidation and adsorption, as well as precipitation. This paper investigates the process with respect to the zeta potential and the size of Cr and As hydroxo complex particles at different pH.
