摘要:

Dibutyltin and tributyltin compounds in artificial sea water were determined at sub-ppb levels. These compounds are separated from matrix elements in aqueous solutions by a simultaneous hydride generation dichloromethane extraction. After dichloromethane is vaporized, the residue is dissolved in hexane and is directly injected into the treated graphite tube and the signal is measured by a Zeeman atomic absorption spectrometer.
