Abstract

The elimination of Zn²⁺ in wastewater by enhanced coagulation was studied with Crosslinked Starch-graft-poly Acrylamide-co-sodium Xanthate (CSAX) cooperating with zeolite. The effects of dosage of CSAX and the particle size of modified zeolite on removal of Zn²⁺ were tested. The experiments results were optimized by introducing the Box-Behnken method. The influence of experimental factors were examined in this order: CSAX dosage >modified zeolite >particle size of modified zeolite. The model equation and experimental data correlated well. The optimum reaction conditions were: 6.4mLCSAX and 12.5mg modified zeolite (with particle size of 60mesh). The removal of Zn²⁺ reached 90% under the optimum conditions, which was consistent with the 89% predicted by the model equation.

Key words： wastewater containing Zn²⁺ enhanced coagulation response surface methodology modified zeolite
