| Research Abstract |
Gelatin and polyethylene glycol were used as additives to make clear the effect of polymer additives on Cu electrorefining and Zn electrowinning. The effect of polymer additives on the deposition behavior, surface morphology and micro structure of Cu and Zn, and suppression effect of harmful impurity by additives were investigated. The effect and degradation behavior of polymer additives were clarified by synergistic effect of Cl^- ions and polymer additives and quantification of molecular weight of additives in electrolytic solution.
