Abstract
Sensors for the qualitative and quantitative determination of K.sup.+ ions in aqueous systems are described, which consist essentially of a carrier and an active layer applied to this carrier, whereby the active layer contains a polymer in which is dispersed at least one modified valinomycin, in which a radical of a fluorescence dye which emits in long waves, preferably an acridine or fluorescein, with an emission wave length of >550, is covalently bound.
