Determination of Tributyltin in Oysters by Electrothermal Atomic Absorption Spectrometry

摘要

Graphite-furnace atomic absorption spectrometry for tributyltin in oysters is described. Tributyltin is extracted byn-hexane after digestion with hydrochloric acid. The 3sgrave detection limit for tributyltin is better than 0.01 mg Sn/kg. Typical absorbance values are about 0.10 for tributyltin contents as low as 0.03 mg Sn/kg. Tributyltin contents of 29 oyster samples are given.
