摘要：

A new method for the determination of triphenyltin (TPhT) in sea-water is proposed. The method is based on solid-phase extraction (SPE), reaction with flavonol in a Triton X-100 micellar medium to yield a fluorimetrically active derivative and excitation-emission fluorescence measurements. TPhT was quantified by an alternating least squares (ALS)-multivariate curve resolution (MCR) procedure and a single synthetic standard. In order to select the optimum conditions for the analysis, the procedure was assessed using synthetic samples. With the proposed method, TPhT was quantified in sea-water samples at low ng l(-1) level with an overall prediction error of around 12%. (C) 2000 Elsevier Science B.V. All rights reserved.
