Abstract
The behavior and stability of organotin compounds in a microwave field is discussed. An extremes rapid procedure for the separation of butyl - and phenyltin derivatives from sediments is developed. The analyte s pecies are quantitatively leached with acetic acid in a focused microw ave field during a period of 3 min. The procedure followed by capillar y GC-FPD offers a detection Limit of 1 ng/g (as Sn). The procedure dev eloped was validated by the analyses of two certified reference materi als: the NRCC PACS-1 and the BCR CRM 462.
