摘　　要：研究了湿法回收废铅蓄电池,并利用其中的有效铅成分制备三碱式硫酸铅。采用正交实验考察了硝酸浓度、物料比、反应时间等因素对回收率的影响。结果表明,湿法回收废铅蓄电池中铅的最佳工艺条件为:硝酸质量分数15%,Pb2+与NO3-物质的量比1∶4,反应时间3 h。合成的产品三碱式硫酸铅质量符合原化工部行业标准(HG2340—1992)。The recovery of lead from waste lead accumulator by wet process and the preparation of tribasic lead sulfate are studied. The effects of concentration of nitric acid, ratio of reactants and reaction time etc. on the recovery rate are investigated by orthogonal test. The results show that the optimum process conditions are as follows. The concentration of nitric acid 15%, n（ Pb^2＋ ） ： n（ NO3^- ） = 1： 4,reaction time 2 h. The quality of the tribasic lead sulfate synthesized can meet the enterprise standard （ HG2340 - 1992）.
