Title:
ELECTROCHEMICAL SENSOR FOR OZONE CONCENTRATION MEASUREMENT
Document Type and Number:
Japanese Patent JP2023181161
Kind Code:
A
Abstract:
To provide an electrochemical sensor that comprises a diamond electrode as a working electrode and a diamond electrode as a reference electrode, and can accurately measure, by linear sweep voltammetry, the ozone concentration in a test solution including ozone at a predetermined concentration.SOLUTION: An electrochemical sensor comprises a first diamond electrode as a working electrode and a second diamond electrode as a reference electrode. In a voltammogram obtained through linear sweep voltammetry measurement performed by bringing the first diamond electrode and the second diamond electrode into contact with a test solution including ozone at a predetermined concentration, a peak corresponding to the ozone concentration in the test solution is observed.SELECTED DRAWING: Figure 1
