摘要
基于国家环境标准"水质无机阴离子的测定离子色谱法"(HJ 84-2016),采用离子交换色谱法对水样中8种无机阴离子(F^-、Cl^-、NO_2^-、Br^-、NO_3^-、PO_4^(3-)、SO_3^(2-)、SO_4^(2-))进行分离分析研究,对氢氧根体系相关的色谱条件进行了探讨。并在优化后的色谱条件下对方法的检出限、准确度和精密度进行了验证,建立了本实验室同时分析水中8种阴离子的方法,为国家标准方法的应用提供参考。
Based on national environmental standard ＂water quality, determination of inorganic anions, ion chromatography＂ （ HJ 84 - 2016 ）, this article researched simultaneous separation and determination of 8 inorganic anions （ F^-, Cl^- , NO2^-, Br^-, NO3^-, PO43^-, SO3^2-, SO4^2- ） in water by ion exchange chromatography, and discussed the related chromatography conditions of hydroxyl system. And the detection limit, accuracy and precision of the method were verified under the optimal chromatographic condition, established the method of simuhaneously analysis 8 inorganic anions in water. It can provide reference for the national environmental standard of HJ 84 -2016.
