CHROMATOGRAPHIC AND HYPHENATED METHODS FOR ELEMENTAL SPECIATION ANALYSIS IN ENVIRONMENTAL MEDIA

This review discusses chromatographic techniques that permit the analy sis of speciated metals in the environment using conventional detector s, such as UV, and element-specific detectors, such as flame atomic ab sorption spectrometry, electrothermal atomic absorption spectrometry a nd inductively coupled plasma mass spectrometry. The importance of det ermining precise elemental forms in hazardous waste-contaminated soil, water and biota in terms of toxicity is outlined. Previous reviews on this subject are described and recent research on this subject is dis cussed. Most of the work cited has been performed in the 1990s and a t able summarizing the chromatographic method and the detector system us ed, including brief comments on the work is included to enable quick r eference.
