Abstract
Abstract A method for the simultaneous determination of butyl- and phenyltin compounds in the aquatic environment was studied. The analytes in water, sediment and biological samples were extracted into 0.1% tropolone-benzene solution after adding hydrochloric acid diluted with tetrahydrofuran. With sediment samples, inorganic sulphur-containing species co-extracted with the analytes were removed with tetrabutylammonium hydrogensulphate-sodium sulphide, which brought about a decrease in many of the accompanying peaks. After propylation with n-propylmagnesium bromide, the analytes were determined by gas chromatography with flame photometric detection. The recoveries were in the range 70–100% and the detection limits for a signal-to-noise ratio of 10 were 3 ng 1−1 in water samples and 0.5 μg kg−1 in sediment and biological samples.
