A study of the mechanism of response of liquid ion exchanger calcium selective electrodes: Part I. Zero current potential of commercial and modified electrodes

A study of the response mechanism of liquid ion exchanger calcium selective electrodes has been undertaken using three different ion exchangers viz. calcium didecyl phosphate, calcium dihydrogen didecyl phosphate in dioctyl phenyl phosphonate and the Orion 922002 solution. The influence of interfering ions has been taken into consideration and reasons given for the past unsuccessful attempts to interpret their effects.
