 note = {A simple and an efficient preconcentration method for the separate determination of each species of chromium {i.e., Cr(III) and Cr(VI)} in environmental water samples has been investigated, followed by inductively coupled plasma-atomic emission spectrometry (ICP-AES). This method is based on the following ion-exchange method. Cr(III) was adsorbed on cation-exchange resin, and Cr(VI) on anion-exchange resin. The retained Cr(III) and Cr(VI) were quantitatively eluted with 2 mol dm^<-3> hydrochloric acid (HCl) and 2 mol dm^<-3> potassium chloride (KCl), respectively. The preconcentration factor was 100 for Cr(III) and 300 for Cr(VI) in this work, and the detection limits were 0.03μg dm^<-3> in Cr(III) and 0.01μg dm^<-3> in Cr(VI). The method has been applied to environmental water samples from Niigata Prefecture. The recoveries of Cr(III) and Cr(VI) in environmental water samples were all 94〜98%, and the effect of interference from the coexistence ion was not detected. Therefore, the above-mentioned method is applicable to environmental water samples.},
