摘　　要：本文采用氯化胆碱-尿素低共熔溶剂体系浸出高炉瓦斯泥,再直接电沉积得到锌.实验考察了液固比、浸出时间、搅拌速度对锌浸出率的影响.浸出实验结束后,我们分别对体系进行了循环伏安测试和电沉积实验.实验结果表明:液固比为10 mL/g,浸出时间为30 h,搅拌速度为300 r/min,温度为70℃的条件下,锌的浸出率达到71%;循环伏安测试确定还原电位为-1.4 V;X射线衍射和能谱分析表明,镀层为纯度较高的金属锌;通过对镀层形貌分析发现电沉积得到了1μm左右团簇状晶粒组成的锌镀层.The choline chloride-urea deep eutectic solvent system was used to leach blast furnace dust,and then zinc was obtained by direct electrodeposition.The effects of liquid-solid ratio,leaching time,and stirring speed on the leaching rate of zinc were investigated.After the leaching experiment,the cyclic voltammetry and electrodeposition experiments were carried out,respectively.The experimental results showed that the leaching rate of zinc reaches 71%under the conditions of liquid-solid ratio of 10 mL/g,the leaching time of 30 h,the stirring speed of 300 r/min,and the temperature of 70℃.The cyclic voltammetry test confirmed that the reduction potential was-1.4 V.X-ray diffraction and energy spectrum analysis showed that the coating was metallic zinc with high purity.By analyzing the morphology of the coating,it was found that the zinc coating was composed of cluster grains of about 1μm.
