An analytical procedure for the determination of trialkyltin (tributyltin, tripropyltin), triphenyltin and dialkyltin (dibutyltin) compounds in environmental water and sediment was studied. Water samples were extracted into benzene with hydrochloric acid and sodium chloride. Sediment samples were extracted into methanolic hydrochloric acid and converted into benzene. Silica gel, which was impregnated with hydrochloric acid and activated, was used for clean-up of these compounds. These extracts of organotin chlorides were hydrogenated with an ethanol solution of sodium borohydride. Organotin hydrides were measured by gas chromatography with electron-capture detection. Recoveries of these compounds were ca. 70-95% from river water and sediment samples. The detection limits were 0.4-0.8 micrograms/l in water and 0.02-0.04 micrograms/g in sediment samples.
研究了一种测定环境水和沉积物中三烷基锡（三丁基锡、三丙基锡）、三苯基锡和二烷基锡（二丁基锡）化合物的分析方法。水样用盐酸和氯化钠萃取到苯中。沉积物样品用甲醇盐酸萃取并转化为苯。用浸渍有盐酸并活化的硅胶对这些化合物进行净化。这些有机锡氯化物的提取物用硼氢化钠乙醇溶液进行氢化。用带电子捕获检测的气相色谱法测定有机锡氢化物。这些化合物在河水和沉积物样品中的回收率约为70 - 95%。水的检测限为0.4 - 0.8微克/升，沉积物样品的检测限为0.02 - 0.04微克/克。
