摘要

初步筛选比较了醋酸中的tropolone(2-羟基-2,4-6-环庚三烯酮)与二乙基二硫代氨基甲酸钠(NaDDC)作为螯合剂对玻璃纤维过滤器和XAD-2树脂管中丁基锡氯化物的萃取效果。后续分析选择NaDDC。将一丁基锡、二丁基锡和三丁基锡加到玻璃纤维过滤器和XAD-2树脂上，用NaDDC在甲苯中提取，用溴化戊基镁衍生化。用气相色谱-等离子体原子发射检测法测定了衍生丁基锡的种类。玻璃纤维过滤器和XAD-2树脂在取样过程中提供了较高的丁基锡化合物保留率，并通过NaDDC提取有效地回收了丁基锡化合物。

A method for the analysis of butyltin chlorides in air by gas chromatography with atomic emission detection.

An initial screening test compared the use of tropolone (2-hydroxy-2,4-6-cycloheptatrienone) in acetic acid with sodium diethyldithiocarbamate (NaDDC) as chelating agents for the extraction of butyltin chlorides from glass fiber filters and XAD-2 resin tube. NaDDC was chosen for subsequent analyses. Mono-, di-, and tributyltin chloride were spiked onto glass fiber filters and XAD-2 resin, extracted in toluene with NaDDC and derivatized with pentylmagnesium bromide. Derivatized butyltin species were determined by gas chromatography with plasma atomic emission detection. Glass fiber filters and XAD-2 resin were found to provide high retention of butyltin compounds during sampling and efficient recovery of butyltin compounds by extraction with NaDDC.
