离子色谱法同时测定酸雨中的钠、铵、钾、镁、钙

Determination of the Sodium,Ammonium,Potassium,Magnesium,Calcium in the Acid Rain by Ion Chromatography

阐述了离子色谱法测定酸雨中的钠、铵、钾、镁、钙含量的方法和步骤。结果表明,各元素的检出限均低于0.02 mg/L,加标回收率为90%~110%,相对标准偏差均低于1%,结果令人满意。该方法可同时测定酸雨中的5种阳离子,并且操作便捷,值得推广与应用。

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.
