海水試料中のジブチルスズおよびトリブチルスズ化合物の分析1に適する試料容器の検討

抄録

The container materials suitable for determination of dibutyltin (DBT) and tributyltin (TBT) compounds in seawater have been studied. Three commercial container materials of glass, polyethylene and polycarbonate bottles were used. One bottle of each material was filled with a stock solution dissolving dibutyltin dichloride (DBTC) and tributyltin chloride (TBTC) in seawater, and the concentrations of DBTC and TBTC were analyzed periodically by gas chromatography with flame photometric detection (GC-FPD). It was found that polyethylene bottle was not suitable for use as seawater container because of adsorption of TBTC on the surface of container, but the glass and polycarbonate bottles were suitable.
