Abstract
A sample preparation procedure is proposed for the analysis of highly alkaline solutions; it includes the addition of a dosed amount of a specially prepared ion exchanger to a container with the analyzed solution, phase equilibration, and the decantation of a liquid phase. The procedure was applied to the determination of the anionic composition of the sample of an alkaline condensate of fumarole gases by ion chromatography.
