Abstract
The use of 3,3',4',7-tetrahydroxyflavone (fisetin) as a post-column fl uorogenic reagent in the determination of tributyltin (TBT) and triphe nyltin (TPhT) by liquid chromatography is reported. TBT and TPhT can b e separated on a cation-exchange column using methanol-water (80:20) c ontaining 0.15 M ammonium acetate as mobile phase. The detection limit s, for 200 mu l of sample injected, are 0.03 and 0.9 ng Sn for TPhT an d TBT, respectively. The method has been applied to the determination of both triorganotin compounds in harbour water and sediments.
