摘　　要：用硝酸-双氧水-氢氟酸作消解酸体系,微波消解法处理样品,采用ICP-AES法测定三聚磷酸铝中重金属铅的含量。测定结果的相对标准偏差小于6%,加标回收率在89.16%～103.85%之间,检出限0.01mg.L-1。该法样品消解完全,元素挥发损失少,测定过程快速,结果准确。The sample was digested by microwave with nitric acid-hydrogen peroxide-hydrofluoric acid as digestion system.Lead in aluminum tripolyphosphate was determined by ICP-AES.The relative standard deviation（RSD） was less than 6%,the recovery of standard addition was between 89.16%～103.85%,and the detection limit was 0.01mg/L.
