説明

A simple and rapid procedure for the determination of tin in environmental samples such as bottom sediments by AAS has been studied. In order to avoid loss of tin compounds by volatilization, decomposition of the sample with a mixture of hydrochloric and nitric acids (3 : 1) was performed in a Kjeldahl flask equipped with a condenser. After decomposition, the solution was filtered and diluted with 1M hydrochloric acid. The atomic absorption of tin was measured in an air-hydrogen fuel-rich flame at 224.6 nm, and the content of tin in the sample was determined by standard addition. This procedure was applied to the determination of tin in bottom sediments of a marine environment at Tanabe Bay, Wakayama Pref. As a result, the contents of tin found in the bottom sediment at Tanabe Bay was estimated to be 8.829.3 μg/g (dry).
