摘　　要： 介绍了利用离子色谱法测定用水中痕量的硝酸根、硫酸根、氯、氟等离子;优化了检测器电流、淋洗液浓度和样品进样量等,使各阴离子的检出限降低,硝酸根、硫酸根、氯、氟等离子的检出限分别为0.016、0.074、0.014、0.012mg/L,加标回收率达到90%~110%;6次检测环境标准204715,相对标准偏差RSD低于2%。离子色谱法测定阴离子方法速度快、精准且灵敏度高,可在同一时间内透析水中不同的阴离子。 This paper introduces the determination of trace nitric acid root,sulfate,chlorine and fluorine plasma in water with ion chromatography,optimizing the current detector,eluent concentration and sample injection volume,etc.,lowering the detection limit of anion,nitrate,sulfate,chlorine and fluorine and other plasma to 0.016,0.074,0.014,0.012mg/L,standard addition recovery of 90% -110%.The environmental standard was 204715,and the RSD was below 2%.The ion chromatography method is used to determine the speed,accuracy and sensitivity of the anion method,which can be used in dialysis water at the same time.
