摘要
用氢氧化钾淋洗离子色谱法同时测定降水样品中的氟离子、乙酸、甲酸、氯离子、硝酸根、硫酸根离子等无机和有机阴离子。该方法简便、快速、精密度好、6种阴离子在12min内全部分析完毕。8次测试的相对标准偏差小于2.8%,检出限在0.39~7.6μg/L之间,加标回收率在94.7%~105.3%之间,能满足降水样品中阴离子的检测,是降水样品中阴离子检测的理想方法。
Determination of organic acids and inorganic anions in rain by ion chromatography.The method is simple,faster,good accuracy and precision,and lower detection limit.The whole analysis process was within 12min.The relative standard deviations were below 2.8%,the detection limit(0.39~7.6μg/L),and the recoveries of anions range were from 94.7% to 105.3%.The method can satisfy the determination of organic acids and inorganic ions of rain sample,and it' an optimal method to determine organic acids and inorganic ions of rain sample.
