摘　　要：用王水溶解试样，在几个相同量的试液中，分别加入浓度依次递增的9种元素的标准溶液。用空气一乙炔火焰原子吸收法连续测定M、Cu、Mn、Fe、Ph、Sb、Zn、Ca、Mg的含量．建立了优化的仪器测定条件，并对可能存在的元素进行了干扰实验．Ni、Cu等9种元素的回收率为97.5％～103．0％，相对标准偏差为1.6％～2．9％．After dissolved by HCl - HNO3, samples were added into the nine elements＇ standard solutions increased by concentration degrees respectively, then the contents of nickel, copper, manganese, iron, lead, antimony, zinc, calcium and magnesium were determined 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 investigated. The recovery was in the range of 97.5% ～ 103.0%. The relative standard deviation was in the range of 1.6% ～2.9%
