Speciation Analysis of Arsenic Based on Hydride Generation

Abstract

This review deals with speciation analysis of arsenic based on hydride generation and coupled with analytical atomic spectrometry. Three basic on-line approaches to speciation analysis of arsenic are defined: (a) selective hydride generation, (b) postcolumn hydride generation and (c) generation of methyl substituted arsanes. All of the approaches are discussed with the focus on the latest advances in those fields.
