ABSTRACT
Meinema et al [1] have described a sensitive and interference-free method for the simultaneous determination of the tri-, di-and mono-butyltin species in aqueous systems at tin concentrations of 0.01-5µg L−1. The species are concentrated from hydrobromic acid solutions into an organic solvent by extractionwith 0.05% tropolene in benzene in the presence of a metal coordinating ligand. The butyltin species in the organic extract are transformed into butylmethyltin compounds by reaction with a Grignard reagent and analysed by a gas chromatographymass spectrometry method. The inorganic tin (IV) species in the organic extract are butylated to tetrabutyltin which is detected by the same technique.
