An optimized sample preparation procedure for organotin speciation in sediment samples has been applied to the analysis of sediments collected in the environment. The method is based on tropolone complexation of the ionic organotins, followed by extraction into a hexane-ethylacetate mixture and derivatization by NaBEt(4). The method was applied to the determination of organotin in various harbour, shipyard and dry-dock sediments in Belgium. Butyltin compounds were detected in all samples analyzed, often at high mg kg(-1) levels. A limited number of samples showed the presence of phenyltin compounds. Further, the method was adapted to the analysis of river sediments sampled from the vicinity of shipyards. Butyltin concentrations were detected at the microg kg(-1) level in the majority of samples.
一种用于沉积物样品中有机锡形态分析的优化样品制备程序已应用于环境中采集沉积物的分析。该方法基于离子有机锡的托酚酮络合，随后萃取到己烷 - 乙酸乙酯混合物中，并通过NaBEt(4)进行衍生化。该方法应用于比利时各种港口、造船厂和干船坞沉积物中有机锡的测定。在所有分析的样品中均检测到丁基锡化合物，其含量通常高达mg kg(-1)水平。少数样品中检测到苯基锡化合物。此外，该方法适用于分析从造船厂附近采集的河流沉积物。大多数样品中丁基锡浓度检测到为μg kg(-1)水平。
