DETERMINATION OF TRIPROPYLTIN CHLORIDE IN ENVIRONMENTAL WATER AND SEDIMENT

An analytical procedure was described for the determination of tripropyltin chloride(TPTC) in the environmental water and sediment. TPTC was extracted into hexane with hydrochloric acid from water sample, and into methanolic hydrochloric acid from sediment sample and converted into hexane. After cleaning up of the extract by the aluminium oxide column with phosphoric acid, TPTC was measured by gas chromatograph with an electron-capture detector. Recoveries of TPTC were 90 to 97 % from water samples and 89 % from sediment samples. The detection limits were 0.30 μg/l in water and 0.015 μg/g in sediment samples.
