摘要样品经王水溶解，聚氨酯泡沫塑料分离富集后，用20 g/L硫脲溶液解析，20 g/L抗坏血酸溶液作基体改进剂，采用石墨炉原子吸收光谱测定钮扣电池中痕量金。优化了石墨炉的测定条件，采用700 ℃和1 700 ℃作为灰化和原子化温度，缩短了测定时间，延长了石墨管的使用寿命。测定结果显示钮扣电池中金含量低于10 ng/g，RSD低于10 %，回收率在88 %～112 %之间，方法检出限为0.15 ng/g，该法适合电子元器件中痕量金的测定。

Abstract： The sample was dissolved by aqua regia, foam separated and enriched by polyurethane, and then analyzed by thiourea solution of 20 g/L. A method for determination of trace gold in button batteries by graphite furnace atomic absorption spectrometry was established.The gold was determined with ascorbic acid solution of 20 g/L as matrix modifier. The detection conditions of graphite furnace atomic absorption spectrometry was optimized with 700 ℃ and 1 700 ℃ as ashing and atomization temperature， respectively ,which shortened the measurement time and extended the life of graphite tube. The results showed that the gold element in button batteries was less than 10 ng/g, RSD was less than 10 % and the recovery was between 88 % and 112 %. Detection limit was 0.15 ng/g. The method was suitable for determination of trace gold in electronic components.

Key words： graphite furnace atomic absorption spectrometry button batteries trace gold thiourea ascorbic acid
