Copper(I) sulphide-impregnated silicone rubber membranes as selective electrodes for copper(II) ions.
Silicone rubber membranes impregnated with copper(I) sulphide have been developed as selective electrodes for coppefr(II) ions. The internal electrode and solution were eliminated. The Nernst equation was satisfied in the concentration range from 10(-1) to 10(-6)M copper(II) and the analytical range was from 10(-1) to 10(-7)M. The interference of other ions was examined. Other resins were compared with silicone rubber as inert matrices.
