▎ 摘　　要

NOVELTY - The solid state ion selective electrode has a solid contact with a conductive layer and a polymer-sensitive film (5) containing an ion carrier. The solid contact conductive layer is a solid powdered magnetic graphene (4) induced to the surface of the electrode substrate by a magnetic adsorption. The magnetic powder of magnetic solid graphene is adsorbed on the surface of the electrode substrate by magnetic induction. The electrode substrate with a solid contact conductive layer is obtained. USE - Solid state ion selective electrode using magnetic field-induced solid contact conductive layer. ADVANTAGE - The electrode has excellent electric potential stability and repeatability. The new idea for the development of solid ion selective electrodes is provided. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of the electrode.
