摘要: An optimized sample preparation procedure for organotin speciation in sediment samples has been applied to the analysis of sediments collected environment. The method is based on tropolone complexation ionic organotins, followed by extraction into a hexane-ethylacetate mixture and derivatization NaBEt 4 . was determination various harbour, shipyard dry-dock Belgium. Butyltin compounds were detected all analyzed, often at high mg kg -1 levels. A limited number showed presence phenyltin compounds. Further, adapted river sampled from vicinity shipyards. concentrations μg level majority samples.
