COMPOSITE ELECTRODE FOR TRANSMITTERS USED IN ECOLOGICAL MONITORING Russian patent published in 1999 - IPC

FIELD: ecological control. SUBSTANCE: invention is related to field of electrochemical methods of analysis of solutions, specifically, to design and process of manufacture of electrodes of second order for potentiometers. Composite electrode is mainly used in production and ecological test of water ( aqueous solutions ) for content of anions S^2-, N^3- and so forth. It includes sensitive element made of base and slightly soluble salt of metal. Base is fabricated from composite metal and polymer current conducting material by method of hot moulding. Slightly soluble salt of metal is located in pores of base in equilibrium with metal included in composition of composite metal and polymer current conducting material. EFFECT: enhanced operational characteristics of composite electrode, simplified manufacturing technology and reduced cost of it. 7 dwg, 2 tbl
