摘要：

A liquid chromatographic method with fluorimetric detection using fisetin as fluorogenic reagent is proposed for the determination of tributyltin (TBT) and triphenyltin (TPhT) in sediments. Ethyl acetate in the presence of an aqueous solution containing hydrochloric acid and sodium chloride is used as extracting system. This method was applied to the assessment of different spiking procedures used to evaluate the recoveries of the analytes. Variables of spiking experiments such as solvent and volume of the spiking solution, equilibration time and type of sediment were studied. The analytical method together with the proposed spiking procedure has been applied successfully to a sediment in an interlaboratory exercise organised by the European Union.
