2.95.13 Miscellaneous
Bruno et al. [842] have described a procedure for the titration of sulphite in non saline
water using standard cerium(IV) as titrant.
Gonzalez et al. [858] have described a method of kinetic multicomponent analysis
based on miscellar analysis for the determination of sulphite and thiocyanate. The method
is based on reaction with 5, 5 ′ -dithiobis (2 nitrobenzoic acid) in aqueous cetyltrimethyl
ammonium bromide miscelles. Down to 0.2-1.5×10 −4 mol L −1 sulphite can be determined
with a relative error of less than 5%.
2.96 Sulphonates
2.96.1 Column chromatography
This technique has been applied to the determination of sulphonates [161].
2.97 Tartrate
2.97.1 Spetrofluorometric method
Bishop [236] has proposed a spectrofluorometric method for the determination of tartrate.
2.97.2 Ion chromatography
The application of this technique is discussed under multianion analysis in section 12.2.4.
2.97.3 Ion exclusion chromatography
The application of this technique is discussed under multianion analysis in section
13.2.1.4.
2.98 Tungstate
2.98.1 Atomic absorption spectrometry
This technique has been used to determine tungstate as the benzoin oxime complex in
methyl isobutyl ketone extracts of non saline waters [859].
2.98.2 Inductively coupled plasma atomic emission spectrometry
Hall et al. [860] preconcentrated tungsten and molybdenum from natural spring water
onto activated charcoal prior to analysis by inductively coupled plasma atomic emission
