Experience with mixed-salt ion-selective sulphate electrodes.
Sulphate ion-selective electrodes with mixed-salt, pressed-pellet membranes have been manufactured and tested for response, stability and selectivity. Acceptable performance was obtained only with selected specimens. The addition of small amounts of cuprous sulphide to the membrane had no significant effect.
