摘　　要：探索了纯水中无机阴离子的种类及其检测方法,采用离子色谱仪测定了不同种类纯水中F^(-)、Cl^(-)、Br^(-)、NO_(3)^(-)、SO_(4)^(2-)、PO_(4)^(3-)六种无机阴离子,精密度实验RSD<1.5%(n=5),标准曲线线性相关系数r>0.99。The content of anions varies with the types of pure water.In this paper,five kinds of inorganic anions in pure water and their detection methods were explored.F^(-),Cl^(-),Br^(-),NO3-,SO_(4)^(2-),PO_(4)^(3-)in different kinds of pure water were determined by ion chromatography.The RSD of precision experiment was less than 1.5%(n=5),and the linear correlation coefficient of standard curve was more than 0.99.
