2.47 Hypochlorite and chlorite
2.47.1 Titration procedure
Gordon [341] had described a procedure for the determination of chlorite and
hypochlorite in amounts down to 0.1mg L −1 by a modified iodometric technique.
2.47.2 Anodic stripping voltammetry
Potentiometric stripping analysis using copper has been employed for the determination
of down to 5µg L −1 hypochlorite in non saline waters [342].
2.47.3 Ion chromatography
The application of this technique is discussed under multianion analysis in section 12.2.5.
