METHOD FOR SENSING THE CHEMICAL STATE OF HIGH-TEMPERATURE COOLING WATER USING ELECTROCHEMICAL WATER CHEMISTRY TECHNIQUE

摘要

PURPOSE: A method for sensing the chemical state of high-temperature cooling water using electrochemical water chemistry technique is provided to improve the efficiency of detecting chlorine ion existence, pH changes, and dissolved hydrogen amount changes in high-temperature water solution by measuring oxidation suppression region changes in a precious metal electrode and the oxidation current in the oxidation suppression region.;CONSTITUTION: A method for sensing the chemical state of high-temperature cooling water using electrochemical water chemistry technique includes a precious metal electrode, a counter electrode, and a device for voltage application and current measurement. The precious metal electrode is made from one selected from the group consisting of Pt, Au, Re, Ru, Rh, Pd, Ag, and Ir or their alloy. The counter electrode is made of a metal or conductive non-metal material, in which high-temperature cooling water flows.;COPYRIGHT KIPO 2011
