Direct Potentiometry of Polyacrylate with Solid-Membrane Cadmium Ion-Selective Electrode [PDF]

Three solid-state ISEs (Cd, Pb, Cu) were evaluated for direct potentiometry of polyacrylate. Cd-ISE had a lower pH response but an appreciably high response to PA, while Cu-ISE had a remarkably high pH response but a rather low response to PA.
