摘　　要：用氢化物原子荧光光谱法测定水消毒剂次氯酸钠中的砷。该方法测定浓度范围可达0．03～100μg／L，拟合标准曲线的相关系数为0．9996，检出限为0．003ug/g，加标回收率在96．0％～104．6％之间，测定结果的RSD在0．26％～2．12％之间，满足水消毒剂检测要求。The hydride atomic fluorescence spectrometry was used to determine arsenic in sodium hypochlorite used as water disinfectant. The results indicated that the method allowed the measurement of arsenic over the range of 0.03 to 100μg/L with a correlation coefficient of 0.999 6 and a detection limit of 0. 003μg/g. The recoveries of the method ranged from 96.0% to 104.6% , and the relative standard deviation ranged from 0.26% to 2.12%. All these could meet the requirements for water disinfectant detection.
