摘　　要：参考我国卫生部生活用水卫生规范及检验规范 ,采用模糊正交设计法 ,建立氢化物原子荧光法测定水中硒的优化实验方法。根据实验优化条件进行水中硒测定 ,硒浓度在 0～ 0 .2 0mg/L范围内有良好线性关系 ,r =0 .9997,检出限为 0 .78μg/L ,相对标准偏差为 2 .3%～ 7.9% ,回收率为 96 %～ 10 5 %。利用该优化的实验条件进行氢化物原子荧光法水中硒测定 ,方法更加准确、灵敏、稳定。Consulting literature and using fuzzy orthogonal design, this research has developed the method to determine selenium in water by hydride generation atom fluorescence spectrometry .The method developed has better linear relative with correlative coefficient of 0.9997 in linear range,detection limit of 0.78μg/L,the relative standard deviations of 2.3%～7.9% and the recovery of standard addition between 96%～105%.The experimental result shows that this method is more accurate,sensitive,stable.
