▎ 摘　　要

NOVELTY - A solid-contact polymer film cadmium ion selective electrode comprises a three-dimensional graphene/mesoporous platinum having a porous structure as an ion-electron conductive layer of a solid contact type polymer film cadmium ion selective electrode, and a sensitive film attached to the ion-electron conductive layer. USE - Solid-contact polymer film cadmium ion selective electrode for detection of heavy metal cadmium ions (claimed). ADVANTAGE - The electrode has high porous structure, good conductivity, fast electronic conductivity, can accelerate the conduction velocity of ion-electron, improve the stability of the electrode conductive layer. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a method for preparing solid-contact polymer film cadmium ion selective electrode.
