Ion chromatography of organic carboxylic acids. Determination of monobasic carboxylic and hydroxy acids
An ion chromatographic method has been developed for the determination of monobasic carboxylic and hydroxy acids, as well as some of their chloroderivatives. The optimum eluent for the joint determination of monobasic carboxylic and hydroxy acids, fluoride and chloride ions is a 1 x 10/sup -4/ M solution of NaOH. The limit of detection of acids with this eluent is equal to (1.5-3.1) x 10/sup -3/ ..mu..g/ml. Inorganic anions (F/sup -/, Cl/sup -/, NO/sub 3//sup -/, and SO/sub 4//sup 2 -/), as well as dibasic carboxylic and hydroxy acids, do not interfere with the determination of monobasic carboxylic and hydroxy acids. The method has been used for the determination of lactic acid in gastric juice and that of formic, acetic, propionic, and butyric acids in water and condensate of thermoelectric power plants.
