      다국어 초록 (Multilingual Abstract)

      Analytical conditions for single column ion chromatographic determination of five anions such as F-, Cl-, NO2-, NO3-, and SO42- were optimized with respect to analysis time and separation efficiency. At the optimum condition of 2.0 mM phthalic acid at pH 4.5, five anions were effectively separated in 10 minutes so that analysis time could be reduced by 40% compared to other recommended conditions. Under this condition all the calibration curves of five anions were linear with a correlation coefficient > 0.999. Analytical results for nine commercial bottled waters were presented.
