14.1.1.1.
2.70 Oxalacetate
2.70.1 Ion chromatography
The application of this technique is discussed under multianion analysis in section 12.2.4.
2.71 Oxalate
2.71.1 Spectrofluorometric methods
There are few fluorometric methods for the determination of oxalate. These methods
have similar sensitivities but the most selective is that using resorcinol [361].
Oxalate has been determined by reduction of non-fluorescent Ce(IV) to fluorescent Ce
(III) [361]. Other reductor ions give the same reaction.
Bishop [236] proposed spectrofluorometric tests for the detection of oxalate.
2.71.2 Ion chromatography
The application of this technique is discussed under multianion analysis in section 12.2.4.
