Abstract
A direct derivatization carried out on sediment slurries and simultane ous speciation of organotin and alkyl lead in sediments is described, Simultaneous determination was performed using dual-channel operation of the AED detector, Direct contact of phentylmagnesium bromide with t he sediment improved drastically the recovery of the monobutyltin (MET ) species, The combined complexation/extraction/derivatization procedu re and the dual-channel AED operation reduced the analysis time. Analy sis of a Certified Reference sediment, PACS-1, demonstrated the accura cy of the method. The absolute detection limits (3 x noise level) are 0.5 pg and 0.2 pg respectively for tin and lead. The relative detectio n limits for sediment (1 g sample) are 2.5 ng g(-1) and 1 ng g(-1) res pectively for organotin and alkyl-lead, expressed as the metal. The re sults of the analysis of some environmental samples are given. (C) 199 7 John Wiley & Sons, Ltd.
