Description
Summary:In this study, the structural characteristic and the adsorption properties of heavy metals on Mongolian natural minerals were investigated. The natural samples were confirmed as Heulandite group of Clinoptilolite type zeolite and clay sample that contains albite and quartz by X-ray diffraction analysis. According to BET surface analysis, natural zeolites have mesoporous type of pore. The results of adsorption study showed that adsorption ability of natural zeolite is high effective for lead ion in acidic aqueous solution and the order of heavy metal selectivity was Pb<sup>2+</sup>&gt;&gt;Zn<sup>2+</sup>&gt;Cd<sup>2+</sup>. The adsorption performance of Arsenic(V) is significantly increased by modification with magnesium oxide on natural zeolite.
