氢化物发生原子吸收光谱法测定纺织品的痕量砷

Trace Arsenic(As) Detection with Atomic Absorption Spectroscope

采用氢化物发生原子吸收光谱法测定纺织品在汗液和唾液中的可萃取砷 ,对氢化物发生条件进行了优选 ,本方法检测限达 0 .2 4 3μg/ m L ,RSD为 4 .64%,加标回收率为 90 .0 %～ 10 1.2 %。

The extractable trace As on textiles by perspiration and saliva was detected by atomic absorption spectroscope. The injection technique adopt hydride generator. The optimized generating conditions of hydride was discussed. The detection limit of this method is 0.243μg/mL, RSD is 4.64%,recovery efficiency is 90.0%～101.2%.
