Solid phase extraction of butyltin compounds in aqueous samples following derivatization in situ with sodium tetraethylborate / F. Yang, X.C. Fang, M. Alaee, Y.K. Chau, National Water Research institute,... : En13-5/98-22E-PDF
"The application of the solid phase extraction (SPE) technique for the pre-concentration of butyltin compounds from aqueous samples is described. The butyltin compounds in water were derivatized in situ with sodium tetraethylborate (NaBEt₄), and extracted by C₁₈ Empore disks. After elution of the disks with a small amount of hexane, the various butyltin species were determined by gas chromatography-atomic emission detection. The high sensitivity and selectivity of the GC-AED system combined with efficient SPE method provided a simple and high quality analytical procedure for the determination of butyltin compounds in aqueous samples. The recoveries of butyltin compounds and tripropyltin (as internal standard) in spiked water were tested under different experimental conditions. The relative detection limit of butyltin compounds in 0.5 L water sample is 1.0 ng Sn/L and recoveries ranged from 78.8 - 92.8%"--Abstract.
