摘要：

建立水样中三丁基锡和三苯基锡同时分析的气相色谱- 火焰光度法。样品经正己烷萃取，四乙基硼酸钠(NaBEt4)衍生化，气相色谱- 火焰光度法测定。线性范围为0.5～10.0mg/L，三丁基锡和三苯基锡相关系数分别为0.9967、0.9982。在10mg/L 和50mg/L 两个添加水平下，平均回收率为72.56%～119.9%，RSD 为3.724%～14.52%。三丁基锡和三苯基锡检测限分别为0.0601、0.1308mg/L。该方法用于自来水中有机锡化合物的测定，取得了较好的效果。

Abstract:

A gas Chromatography method was developed for the determination of tributyltin and triphenyltin in water. The samples were extracted by hexane, derivatived by NaBEt4 and determined by gas chromatography-flame photometric detection (GC-FPD). This method showed good linearity within the range of 0.5－10.0 mg/L and the correlation coefficient R2 were 0.9967 and 0.9982 for tributyltin and triphenyltin, respectively. In the two spiked level of 10 mg/L and 50 mg/L, the average recovery was 72.56%－119.9% and RSD was 3.724%－14.52%. The detection limit of tributyltin and triphenyltin were 0.0601, 0.1308 mg/L, respectively. The method was simple and feasible for the determination of organotin compounds in tap water with satisfactory results.
