COMPOSITE MATERIAL FOR SENSITIVE ELEMENT OF COBALT-SELECTIVE ELECTRODE

摘要

FIELD: electricity. ^ SUBSTANCE: invention is related to the field of electrochemical analysis of solutions, namely, to procedure of ion-selective electrode manufacture for direct potentiometry. Composite electrode may find application in industrial, ecological and medical control of aqueous solutions for content of Co2+ ions. Composite material for cobalt-selective electrode represents ion-sensitive element. As basis metal-polymer electroconductive material is used, which contains superdispersed particles of cobalt in polymer matrix prepared by chemical deposition of cobalt particles on the surface of thermoplastic polymer microspheres with further hot pressing. ^ EFFECT: simplification and cost reduction of manufacturing technology of ion-sensitive element (composite material) for creation of solid-state cobalt-selective electrode with improved operational characteristics. ^ 2 dwg
