摘　　要：用HNO_3溶解试样,配制6种元素混合标准系列溶液,用空气-乙炔火焰原子吸收法连续测定Pb,Cd,Fe,Cu,Sb和Mn的含量。建立了优化的仪器测定条件,并进行了相关的干扰实验。方法的回收率为98.9％～102.0％,相对标准偏差为1.8％～2.5％。After the sample was dissolved by nitric acid, a series of mixed standard solutions of the six elements were made up, then the contents of lead, cadmium, iron, copper, stibium, manganese were determined successively by air- acetylene fire atomic absorption spectrometry (FAAS) .The optimum determination conditions have been established. The interference tests for other elements that probably exist have been conducted.The rate of recovery is 98.9% - 102.0% .the relative standard deviation is 1.8% - 2. 5%.
