 abstract={Chromium exists primarily in two oxidation states. The different toxicities and bioavailabilities of Cr(III) and Cr(VI) are public health concern and therefore require strict control. Some AAS/ICP methods work according to the so-called difference method and they do not allow the simultaneous determination of chromium(III) and (VI). The need of more accurate and rapid analysis of environmental samples has led to investigation of ion chromatography as an alternative to wet chemical chromium analyses. Conventional HPLC, photometric methods and atomic absorption spectroscopy analyse are less interference free than ion chromatography which has been used in a wide variety of chemical species. At present analytical chemists focus on alternative Cr(III)+Cr(Vl) methods which will be faster, more sensitive and cheaper than spectroscopic methods and which will allow to exclude many matrix interferences. This paper describes investigations of application of PDCA as a complexing agent of Cr (III) ions and its using in simultaneous determination of Cr(III) and Cr(VI) in water by means of ion chromatography with UV detector.},
