Abstract

We have worked out several chromium speciation and pre-concentration methods with the use of the GFAAS technique. These methods were based on classical and continuous liquid-liquid extraction techniques using a patented continuous extraction device. For the separations and enrichments of chromium species was used ion-pair compound. As an application we have determined the Cr(III) and Cr(VI) content of water using these separation/enrichment methods and the GFAAS technique. The advantage of these methods is the cost effectiveness, high chromium species enrichment and easy use with GFAAS technique, therefore the concentration of the chromium species can be determined at the ng/L level.
