Anions in high purity, boiler feed and nuclear
reactor cooling waters
11.1 High purity waters
11.1.1 Carbonate
11.1.1.1 Ion chromatography
Carbonate has been determined in high priority water in amounts down to 0.02µg L −1 by
ion chromatography on Zipax SAX phthalic acid or mucomic acid at pH 6.5 and 7.2 as
eluting agent and an indirect ultraviolet detector set at 321µm [1].
11.1.2 Chloride
11.1.2.1 Spectrofluorometry
Fluorescence spectroscopy has been used to determine down to 1µg L −1 chloride in high
purity water. The method is based on the quenching effect of silver chloride on the
fluorescence of sodium fluorescein. The coefficient of variation is within 15% at the
10µg L −1 chloride level [2].
11.1.2.2 Ion chromatography
The application of this technique is discussed under multianion analysis in section 12.9.1.
11.1.3 Nitrite
11.1.3.1 Ion chromatography
The application of this technique is discussed under multianion analysis in section 12.9.1.
11.1.4 Sulphate
11.1.4.1 Molecular emission cavity analysis
Sulphate has been determined in high purity water by molecular emission cavity analysis
