摘　　要：利用AFS-9330双道原子荧光光度计测定水中的锡，以1．0％的盐酸作为载流液、1．O％的硼氢化钾为还原剂，荧光强度与其质量浓度在0～40μg/L范围内，线性良好，相关系数为0．9992，方法检出限为0．06μg/L。相对标准偏差在1．79％～2．83％之间，加标回收率为91．0％～103％。A study was performed to determine Tin in surface water using AFS-9330 double channel atomic fluorescence spectrometer. In the analysis process, 1.0% hydrochloric acid solution was used as carrier liquid and 1.0% potassium borohydride （KBH4） was used as reductant. The results indicated that the detection limit of the method was 0.06 μg/L and the relative standard deviations were from 1.79% to 2.83%. The linear range of the method was 0～40μg/L and the related coefficient was 0.999 2. The adding standard recovery rates of the method were 91.0%-103%.
