Abstract
The Orion cupric ion electrode exhibited the theoretical (Nernstian) response of 29–30 mV per concentration decade in deionized water solutions, but in certain moderately alkaline and moderately saline natural waters of the Canadian prairies (pH 7.8–8.6, specific conductance 950–6550 μS/cm) the response to added cupric ion of over 100 μg Cu/L was twice as great. The electrode was, nevertheless, usable in natural waters provided that calibration was made with water from the same source.
