Abstract

In this paper, the flocculant and trapping performance of the crosslinked starch-graft-polyacrylamide-co-sodium xanthate (CSAX) was evaluated using wastewater that contains Hg²+ as the target. Some factors affect the removal rate of Hg²+ were investigated. The experimental results show that the CSAX was successfully synthesized and it has functions of removing both turbidity and Hg²+ from aqueous solution. With the increase of pH value and CSAX dosage, the removal rate of Hg²+ is increased gradudlly. If the presences of alkali metal and alkaline-earth metal ions in wastewater, the removal rate of Hg²+ is improved too. Then the presences of SO₄²- and EDTA in wastewater inhibit the removal rate of Hg²+. Meanwhile when Hg²+ and turbidity coexist in the wastewater,the removal rate of Hg²+ can be promoted.
