摘　　要：用HCl HNO3 KClO3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3种元素的标准溶液,用空气 乙炔火焰原子吸收法连续测定Co,Ni和Cu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。钴、镍、铜的回收率为98 3%～101 0%,相对标准偏差为0 76%～2 31%。After samples were dissolved with HClHNO3KClO3,the standard solutions of cobalt,nickel and copper with concentration increased by degrees were added into the several same samples,respectively. Then cobalt,nickel and copper contents were determined successively by airacetylene flame atomic absorption spectrometry(FAAS)The optimum condition for determination was establishedThe interferences probably by the coexisting elements have been investigated The recovery for the three elements was in the range of 983%-1010%The relative standard deviation was in the range of 076%-231%
