摘要
采用Na_2S_2O_8氧化处理高钴锌电解液。结果表明,加入理论量4倍的Na_2S_2O_8后,在pH 4.0、80℃反应120 min,钴的沉淀率为99.8%,沉钴物的主要物相为CoO(OH)(羟基氧化钴)。沉钴后液除镉、镍后可用于后续电解锌。
Oxidization treatment of zinc sulfate solution bearing high cobalt by sodium persufate was studied. The results show that cobalt precipitation rate is 99.8% under the optimum conditions including dosage of Na2S208 of four times of theory value, pH value of 4.0, temperature of 80 ℃, and reacting time of 120 rain. The main phase of precipitation is CoO（OH）. The residual solution can be used for zinc electrolysis after removal of cadmium and nickel.
