A method with unusual selectivity has been developed for determi-nation of common anions such as chloride, bromide, nitrite, sulfate, phosphate, and iodide. The method uses with reversed-phase columns (graphite carbon and ODS), coated with fluorine-containing surfactant, and conductivity detection. A graphitized carbon column was selected for this study because of its high chemical stability, reliability, and reproducibility. Separation of common anions was achieved in 12 min. Calibration plots of peak area against anion concentrations were linear in the range 1–15 µg mL-1 for Cl-, 1–20 µg mL-1 for Br- and SO42-, and 3–20 µg mL-1 for I- and NO3-, with good correlation coefficients (r2 = 0.9922). Detection limits calculated for a signal-to-noise ratio (S/N) of 3 ranged from 0.76 to 0.98 µg mL-1. The reproducibility of retention times was varied from 0.28 to 0.45 relative standard deviation (RSD,%) and reproducibility of chromatographic peak areas was 2.13–3.25 (RSD,%).The method was successfully applied to the determination of anions in acid rain and related natural waters, including rain, river, and underground water.
