Paper Abstract

We have developed a new technique for detecting the concentration of Cl in aqueous solution. The concentration of CF is determined by measuring the absorbance of C12 which is formed by ArF laser irradiation. The absorption maximum of C12 is located at 340 nm. A linear relationship between the absorbance and the concentration on a log-log scale was confirmed. The detection limit of 1x10-5 M has been achieved. This method is applicable to real-time and in-line measurement, and to other halogen ions.
