Abstract:
An apparatus for detecting anions in water with the use of an electric conductivity cell, which comprises an electrolyzer constituted by an anode chamber having an anode plate and a cathode chamber having a cathode plate via a cation exchange membrane, a direct-current power unit for applying a direct-current voltage between the anode and the cathode of the electrolyzer, and an electric conductivity cell for measuring the electric conductivity of a sample water, and a flow passage for introducing the sample water into the anode chamber and a treated water flow passage for discharging the treated water which has been subjected to electrolytic treatment in the anode chamber of the electrolyzer which are connected to the anode chamber, respectively, and the treated water flow passage being connected to the cathode chamber via the electric conductivity cell.
