摘　　要：监测降水各种离子特别是F-、Cl-、NO3-、SO24-等阴离子的含量,是研究酸雨危害的前提条件[1]。离子色谱分析具有高灵活性、高选择性、高灵敏度的特点,已经广泛应用于环境等众多领域,是测定很多阴离子和阳离子的有效方法[2];但离子色谱仪在调节和分析过程中还存在许多影响因素,从而对实验结果产生影响。为此,本文对ICS-90型离子色谱仪在降水中F-、Cl-、NO3-、SO42-阴离子分析中出现的三个主要影响因素进行了初步研究和探讨。Monitoring of precipitation of various ions,especially F^-,Cl^-,NO^-3,SO4^2-and other anion concentration were a prerequisite for study of hazards of acid rain.Ion chromatography with the characteristics of high flexibility,high selectivity,and high sensitivity was widely used in many fields.It was an effective way to determine the number of anions and cations.But in the regulation and analysis of ion chromatography,there were many influencing factors on the experimental results.So,the preliminary research and discussion were conducted with ICS-90 Ion Chromatography on three influencing factors of F^-,Cl^-,NO^-3,SO4^2- anion analysis of acid precipitation.
