| Abstract: | This paper describes the methods and steps on the ion chromatographic to determine sodium,ammonium,potassium,magnesium,calcium content in acid rain.The results show that the detection limit for each element were below 0.02 mg/L,recoveries were 90% to 110%,relative standard deviations were less than 1%,with satisfactory results.This method can be simultaneous determination of five kinds of cations in the acid rain,and the operation is convenient,worthy of promotion and application. |
