离子色谱法同时测定饮用水源中七种阴离子

Simultaneously Determination of Seven kind of Anions in the Source of Drinking Water with Ion Chromatograph

本文通过研究建立了离子色谱法同时测定水中F-、CL-、NO2-、Br-、NO3-、H2PO4-、SO42-七种离子的方法,方法的检出限低、灵敏度高、线性范围广、抗干扰强、操作简便,可快速同时测定不同数量级浓度的离子。有效地满足饮用水安全保障预警体系中对源水、出厂水进行无机消毒副产物和其他控制阴离子的快速检测。

This article established the ion chromatography through the research simultaneously to determine the water F^-, CL^-, NO2^-, Br-, NO3 ^-, H2PO4^ -, SO4^2- seven ion methods, the method picks out limits, the sensitivity high, the linearity range to be broad lowly, the anti -jamming was strong, the operation was simple, but fast simultaneously determined the different magnitude density ion. Satisfies in the tap water safety eontrol early warning system to the source water, the leaving the plant water tO carry on the inorganic disinfection by - product and the other control anion fast examination effectively.
