It examined about the method of the HPLC post-column derivatization which used the reaction reagent of the chromotropic acid to analyze small amount boron in various water samples, and it developed the HPLC system of analyzing simultaneously with the inorganic anions such as fluorine, chlorine, nitric acid, nitrous acid, sulfuric acid and boron.<BR>This method was separated an component of anions by column of HPLC and after analyzing a fluorine, chlorine, nitric acid, nitrous acid and sulfuric acid with the conductivity detector, it analyzed boron with the fluorescence detector at ex. 330nm and em. 355nm by the method of the post-column derivatization.<BR>It compared about the measurement value of this method, the ICP emission spectrochemical analysis and other method for boron in environment samples. As a result, the measurement value of this method and ICP agreed.<BR>It seems to be effective as the simultaneous analysis method of inorganic anions such as fluorine, chlorine, nitric acid, nitrous acid, sulfuric acid and boron in the tap and river water.
