| 摘 要： | 采用简易氢化法应用于电感耦合高频等离子体原子发射光谱仪（ＩＣＰ—ＡＥＳ）同时测定了人发中的痕量元素硒、砷，所用氢化物发生装置，具有结构简单、操作方便的特点。该方法的检出限为硒１．２ｎｇ／ｍＬ，砷１．０ｎｇ／ｍＬ，在１．０μｇ／ｍＬ浓度下，其相对标准偏差分别为３．９％和２．１％，回收率为９５．１％和９２．３％。应用于饮用水、茶叶等环境和生物样品中硒、砷的测定，均取得令人满意的结果。

| Abstract: | A method for the determination of Se and As in human hair by hydride generation inductively coupled plasma--atomic emission spectroscopy is described. The optimum working parameters were obtained by experiments,and the detection limits of selenium and arsenicwere 1, 2ng/mL and 1. 0ng/mL,respectively. The method was simple and rapid,and results were satisfactory. |
