研究了水环境中丁基锡和苯基锡化合物的同时测定方法。水、沉积物和生物样品中的分析物经四氢呋喃稀释的盐酸溶液提取后，用0.1%托酚酮-苯溶液萃取。与沉积物样品中，无机含硫物种共提取的分析物与四丁基硫酸氢铵-硫化钠，这带来了许多伴随的峰的减少被删除。用正丙基溴化镁进行丙基化后，用气相色谱-火焰光度检测器进行测定。回收率在70-100%之间，信噪比为10时，水样中的检出限为3 ng 1− 1，沉积物和生物样品中的检出限为0.5 μg kg− 1。
A method for the simultaneous determination of butyl- and phenyltin compounds in the aquatic environment was studied. The analytes in water, sediment and biological samples were extracted into 0.1% tropolone-benzene solution after adding hydrochloric acid diluted with tetrahydrofuran. With sediment samples, inorganic sulphur-containing species co-extracted with the analytes were removed with tetrabutylammonium hydrogensulphate-sodium sulphide, which brought about a decrease in many of the accompanying peaks. After propylation withn-propylmagnesium bromide, the analytes were determined by gas chromatography with flame photometric detection. The recoveries were in the range 70–100% and the detection limits for a signal-to-noise ratio of 10 were 3 ng 1−1in water samples and 0.5 μg kg−1in sediment and biological samples.
