浅析河道水中电导率对CODMN的影响

摘要

CODMN Standard Test method,when the chloride ion concentration is less than 300mg/l with acid method,otherwise with the alkaline method.The in Taizhou into the river river water as the object of study proved the water conductivity and chloride ion correlation between,confirmed that the conductivity is greater,the greater the impact on the acidic potassium permanganate method, and the work for online monitoring of CODMn acid or alkaline method provides a theoretical basis and technical basis.%CODMN标准测定方法，当氯离子浓度小于300mg/L用酸性法，否则用碱性法。本文以台州入江河道水体作为研究对象，探明了水体中电导率和氯离子之间相关性，证实了电导率越大，对酸性高锰钾法影响越大，这项工作为在线监测CODMN酸性法或是碱性法提供了理论基础和技术依据。
