ABSTRACT:
An electrode that is specific for the isocyanurate ion, and capable of rapid determination of the free isocyanurate ion activity directly in solution uses as its sensing element a platinum wire covered with a polyvinyl chloride membrane. The membrane is plasticized with a solution of a quaternary ammonium salt of isocyanuric acid. When this electrode and a commercial reference electrode are immersed in a solution containing the isocyanurate ion, a differential voltage proportional to the isocyanurate ion concentration is generated which is detected by a pH meter.
