摘要：

Matrix removal and preconcentration of metals from liquid samples were obtained with a solid-phase extraction/slurry-sampling procedure applied to inductively coupled plasma-atomic emission spectrometry (ICP-AES) detection. A polymeric, adsorbing resin (Amberlite XAD-2), dispersed in the sample, was used for total sorption of analytes previously complexed with a dithiocarbamate ligand. After filtration, the resin was recovered and re-dispersed by means of a non-ionic surfactant; metals retained were determined with the slurry-sampling technique. All parameters were optimised to yield a solution-like signal from the final dispersion. (C) 1998 Elsevier Science B.V. All rights reserved.
