Abstract

Vanadium titanium steel slag (VTSS) containing transition metal can promote the adsorption of Hg⁰. The method of KBr and KI impregnation was applied to modify VTSS and the properties of the adsorbents were tested. The Hg⁰ removal tests were carried out with a fixed bed under different conditions. The results showed that the Hg⁰ adsorption capacity increase with the increasing temperature. The efficiency was highest with KI(3)/VTSS at 20^。C and adsorption capacity was 163.4 ug/g after 3 h. The highest Hg0 removal efficiency were 90.6% for KI(3)/VTSS, 73.5% for KBr(10)/VTSS/ VTSS at 120^。C, respectively.
