Determination of chloride, nitrate, sulphate and total sulphur in environmental samples by single-column ion chromatography.
The analytical performance characteristics of a single-column ion chromatography system are reported. The data were obtained by using conductivity detection as well as by an indirect ultraviolet technique. The method has been applied to the determination of Cl(-), NO(3)(-) and SO(4)(2-) in samples of rain, sewer water, and soil-pore water. Also described are two methods which allow ion Chromatographic analysis of CaS0(4)-extractable nitrate in soils, and total sulphur in soils, marine sediments and plant tissue.
