Ion selective electrode comprising cuprous sulfide and method of making said electrode
Abstract
Abstract AN ELECTRODE ASSEMBLY FOR DETECTING IONS IN SOLUTION HAVING AN ION-SENSITIVE IMPOROUS MEMBRANE CONSISTING OF A COMPRESSED PELLET COMPRISING A MIXTURE OF CUPROUS SULFIDE AS THE CONDUCTIVE MATRIX MATERIAL DISTRIBUTED THROUGH A SALT CONTAINING IONS TO WHICH THE ASSEMBLY IS SENSITIVE, SUCH AS SILVER CHLORIDE WHEN CHLORIDE IONS ARE DETECTED, IS DISCLOSED. IN THE ION-SENSITIVE ELECTRODE ASSEMBLY THE MEMBRANE IS EXPOSED AT ONE SURFACE TO THE SOLUTION IN WHICH THE ELECTRODE IS IMMERSED AND THE SELECTED ION CONTENT THEREOF IS TO BE MEASURED, THE OTHER SURFACE BEING IN CONTACT WITH AN OCCLUDED ELECTROLYTE IN WHICH A CONTACT WIRE IS IMMERSED TO PROVIDE A FIXED CONTACT POTENTIAL. THE ION-SENSITIVE ELECTRODE AND A STANDARD REFERENCE ELECTRODE ARE BOTH CONTACTED WITH THE SOLUTION OF IONS TO BE MEASURED AND ARE CONNECTED TO A POTENTIAL MEASURING DEVICE SUCH AS A VOLTMETER.
