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.
