摘要
应用火焰原子吸收光谱（FAAS）法测定了钮扣电池中铅和镉的含量，对测定条件作了较详细的研究。用在线双毛细管标准加入法消除了基体的干扰。按所述方法测定电池样品中铅和镉，测定结果的RSD依次为3．58％和5．87％，铅和镉的浓度水平分别为5．4×10^-3％和2．3×10^-4％（质量分数），回收率结果为93．0％-100．1％（铅）和95．0％-101．0％（镉）。
Flame-atomic absorption spectrometry was applied to the determination of lead and cadmium in bulton-shaped cells, and the optimum conditions of the method were studied. Matrix interference was eliminated by the standard addition method, which was performed by the binary capillary technique under on-line mode. The working conditions of the instrument were also described in detail RSDrs of results obtained by the present method were 3.58% for lead and 5. 87% for cadmium at the concentration levels of 5. 4 × 10^-3% and 2. 3 × 10^-4 respectively. Results of recovery test were in the ranges of 93.0%-100. 1% （for Pb） and 95. 0%-101.0% （for cadmium）.
