摘　　要：为了明确铅电解常用添加剂骨胶的最佳浓度以及胶体杂质对铅电解的影响,从溶液浑浊度、电流效率、电耗及析出铅形貌等方面对电解液进行评估,研究了电解液骨胶浓度、骨胶溶液静置时长以及活性炭净化处理液固比对铅电解的影响。结果表明,适宜的骨胶浓度为0.8 g/L;将铅电解配制所用骨胶溶液静置72 h或经1000∶1活性炭净化均能去除胶体杂质,净化后铅电解液的电流效率高达99.19%,电耗降至51.79 kW·h/t,获得的析出铅表面平整光滑。In order to obtain the optimal concentration of bone glue as a commonly used additive for lead electrolysis and also understand the influence of its colloidal impurities on lead electrolysis,the effects of the concentration of bone glue in the electrolyte,the standing time of bone glue solution and the liquid-solid ratio for purification with activated carbon on lead electrolysis were investigated by evaluating the turbidity of the solution,current efficiency,power consumption and the morphology of precipitated lead.It is found that the optimal concentration of bone glue in lead electrolyte is 0.8 g/L,and colloidal impurities can be removed by resting the bone glue solution for 72 hours or by purifying it with activated carbon in a ratio of 1000∶1.After purification,lead electrolyte has its current efficiency up to 99.19%.The power consumption of electrolysis declines to 51.79 kW·h/t,and the obtained precipitated lead has a flat and smooth surface.
