A method for the simultaneous preconcentration of chromium(III) and chromium(VI) in aqueous solution using an anion-exchange resin was developed. After chelating with EDTA, chromium(II1) was bound to Dowex l-X8 anion-exchange resin under the controlled conditions. Chromium(W) was then enriched on th

This paper describes the development of an ion chromatography system for the separation and determination of Cr(II1) and Cr(VI) species in aqueous samples. The separation was carried out on a Dionex AS4A anion exchange column containing a small proportion of cation exchange groups. Very high sensiti
## Abstract We have developed new supported liquid membrane (SLM) technology for removal and recovery of chromium from waste waters. The technology not only removes the Cr (VI) to less than 0.05 ppm in the treated effluent allowable for discharge or recycle, but also recovers the product at a high
