[Cation selective electroanalysis of K(+)-, Na(+)- and Ca2(+) concentrations in acetate dialysis solutions].
An account is given on the influence of acetate ions in direct potentiometric analyses of dialytic solutions using K+, Na+ and Ca2+ selective carrier PVC solid contact sensors. By calibrating the flow-through membrane electrodes with anion-corrected solutions, the deviation of ion concentrations based on the acetate effect can be eliminated. The phenomena observed are attributed primarily to an acetate anion interference.
