Anions in non saline waters
2.1
Acetate
2.1.1
Titration method
Hasson
et al.
[1] have used a potentiometric gas sensing probe for the selective
potentiometric determination of acetate in non saline waters.
2.1.2
Ion chromatography
The determination of acetate by this procedure is discussed under multianion analysis in
sections 12.2.4 and 12.2.5.
2.1.3
High performance liquid chromatography
The determination of acetate by this procedure is discussed under multianion analysis in
section 13.1.1.5.
2.2
Amino-acetate
2.2.1
Electrophoresis
Yu and Dovichi [2] used capillary zone electrophoresis with thermo-optical absorbance
detection to determine sub µg L
−1
concentrations of 18 amino acids.
2.2.2
Gas chromatography
Gardner and Lea [3] preconcentrated free and combined amino acid from lake water on
an ion exchange column, prior to desorption with a small volume of acid followed by
conversion to N-trifluoroacetyl methyl esters and gas chromatography.
2.3
Anisate
2.3.1
Ion chromatography
The determination of anisate by this technique is discussed under multianion analysis in
section 12.2.5.
