Photoinduced Potential Changes across Poly(vinyl chloride)/Crown Ether Membranes. Membrane Potential in the Presence of Alkaline Earth Metal Cations

Abstract
The potential change across poly(vinylchloride)/crown ether membrane was induced by photoirradiation in the presence of alkaline earth metal cations. The photoresponse of the membrane potential depended markedly on the kind and concentration of the cation species, the magnitude of the potential shift lying in the order of Mg2+>Ca2+≈Sr2+>Ba2+.
