The invention relates to detection of heavy metal copper ions, in particular to preparation and application of a solid contact type polymer thin film copper ion selective electrode. The bottom of the electrode base body is successively provided with an ion-electron conducting layer and a polymer sensitive film with the thickness of 2.5-10 microns; The ion [i] electron conduction layer is ordered mesoporous carbon, wherein the ion [i] electron conduction layer is an ordered mesoporous carbon. The electrode can effectively inhibit diffusion of main ions from the membrane interface layer to the membrane body, so that more main ions are accumulated on the surface of the membrane, potential response signals are enhanced, and the purposes of reducing the detection limit of the electrode and improving the sensitivity are achieved.
