摘　　要：研究了废锌锰电池正负极电极材料在硫酸中的溶解情况。H2O2的加入会对溶解过程产生较大的影响,适宜的溶解条件为:硫酸浓度3mol/L,液固比为6,反应温度50℃,H2O2浓度2.5%(质量分数),反应时间20min。Described an experiment to analyze and study the polar-materials in waste Zn-Mn batteries leached by sulfuric acid under different conditions. The dosage of H2O2 had significant effects on the dissolution. The suitable conditions were obtained by orthogonal experiments, such as： the concentration of sulfuric acid 3 mol/L, the mass ratio of liqud to solid 6, dissolution temperature 50 ℃, the mass fraction of H2O2 2.5%, dissolution time 20 min.
