摘要：

The use of 3,3',4',7-tetrahydroxyflavone (fisetin) as a post-column fluorogenic reagent in the determination of tributyltin (TBT) and triphenyltin (TPhT) by liquid chromatography is reported. TBT and TPhT can be separated on a cation-exchange column using methanol-water (80:20) containing 0.15 M ammonium acetate as mobile phase. The detection limits, for 200 mu l of sample injected, are 0.03 and 0.9 ng Sn for TPhT and TBT, respectively. The method has been applied to the determination of both triorganotin compounds in harbour water and sediments.
