Several inorganic anions in environmental water samples, such as river, rain, tap, and waste waters, were determined by capillary electrophoresis with indirect photometric UV detection. In this study, the use of a polymer coated silica capillary and an anionic organic photometric reagent realized a stable baseline and short analytical time. Nine kinds of anions, Cl(-), Br(-), NO(3)(-), SO(4)(2-), C(2)O(4)(2-), ClO(4)(-), F(-), HPO(4)(2-), and HCO(3)(-), were well separated and detected within 12 minutes. Calibration graphs for the anions showed a good linearity in the range of 0 to 4x10(-4) mol dm(-3). Detection limits of the anions were 2x10(-6) mol dm(-3) (HPO(4)(2-)) to 4x10(-5) mol dm(-3) (NO(2)(-)). Anions in river water (Zasu river) and waste water (Okayama University, North district) were measured over 5 days. The waste water contained various kinds of anions, at high concentrations with its large variation, when compared with the river water. The proposed method offers a simple, rapid, and accurate analysis of anions in water samples.
