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。

摘  要：
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.
