摘　　要：用HCl-H2 O2 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 6种元素的标准溶液 ,用空气 -乙炔火焰原子吸收法连续测定Fe,Sb ,Mn ,Cu ,Ca和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试验。铁等 6种元素的回收率为 97 8%～ 10 3 7% ,相对标准偏差为 1 9%～ 3 5 %。After the sample was dissolved with HCl-H 2O 2, the standard solutions of six elements with concentration increased by degrees were added into several same samples, respectively, then the contents of Fe, Sb, Mn, Cu, Ca, Mg were determined successively by air acetylene flame atomic absorption spectrometry (FAAS). The optimum condition for determination was established. The interference probably coexisting elements has been investigated. The recovery of 6 elements determined was in the range of 97.8%-103.7%. The relative standard deviation was in the range of 1.9%-3.5%.
