摘　　要：通过调整钼测试溶液pH值,使钼在溶液中存在形态一致(MoO24-),并选用高纯试剂三氧化钼为基准物质标定硝酸铅标准溶液,提高方法的准确度。用所拟的沉淀滴定方法测定工业钼酸铵中钼含量,快速、准确、精度高,未见文献报道。滴定产物可回收利用钼,废液无毒,排放无碍环境保护。The existing morphology of molybdenum in solution is identical by adjusting molybdenum to test pH value of solution. Lead nitrate standard solution is demarcated by choosing high - purity reagent MoS2 as datum with high accuracy. Molybdenum content in industrial ammonium molybdate is determined by precipitation titration rapidly and accurately. Titration outcome can be recovered and waste liquid is poisonous.
