Abstract: Soils from different places and depths were dissolved in water, and under the optimal conditions, the contents of sulfate and nitrate were determined by ion chromatography. The results showed that:the relative standard deviations were 1.9% and 3.0%, the recoveries of sulfate and nitrate were 90.0%~100.0% and 93.0%~101.0%, respectively. The method is simple and rapid.The precision and accuracy are in accordance with the requirement of sulfate and nitrate determination for soil test.
