Analysis of Oxyhalides and Anions in Tap Water (SI-52 4E)

Please use this column with suppressor type ion chromatography system.

Chloric acid should be analyzed by ion chromatography for water quality control in accordance to the Ministry of Health, Labor and Welfare in Japan. The method states an addition of 1mL ethylenediamine solution (50 mg/mL) to 1L of sample collected. This prevents chlorous acid from reacting with residual chlorine to form chloric acid. Oxyhalides and anion standards in river water were analyzed using IC SI-52 4E.
