This article presents different strategies for separation and pre-concentration of arsenic species based on classical ion-exchange column chromatography by means of the strong cation or anion-exchange resins used in the analytical atomic spectrometry in the last 30 years. In addition, some aspects of sample pre-treatment, including preservation and extraction of arsenic species, are highlighted.
