Abstract 1. A METHOD OF MEASURING THE CONCENTRATION, IN AQUEOUS SOLUTION, OF HYDROPHOBIC ORGANIC IONS SELECTED FROM THE GROUP CONSISTING OF HYDROPHOBIC ORGANIC ANIONS AND CATIONS, WHICH METHOD COMPRISES (A) CONTACTING SAID SOLUTION CONTAINING SAID ORGANIC ION WITH (1) A POLYMER MEMBRANE HAVING DISPERSED THEREIN A COMPATIBLE ORGANIC PLASTICIZER WHICH SELECTIVELY SOLVATES SAID IONS SELECTED FROM THE GROUP CONSISTING OF ORGANIC PLASTICIZERS CONTAINING ACIDIC HYDROGENS AND ORGANIC PLASTICIZERS CONTAINING AVAILABLE ELECTRON PAIRS, SAID MEMBRANE ENCLOSING AND BEING IN ELECTRICAL CONTACT WITH A FIRST STANDARD REFERENCE ELECTRODE OF KNOWN POTENTIAL, AND (2) A SECOND STANDARD REFERENCE ELECTRODE OF KNOWN POTENTIAL; (B) ESTABLISHING A POTENTIAL VOLTAGE BETWEEN SAID FIRST AND SECOND ELECTRODES; AND (C) MEASURING SAID POTENTIAL VOLTAGE, WHEREIN SAID POTENTIAL VOLTAGE IS PROPORTIONAL TO THE LOGARITHM OF THE CONCENTRATION OF SAID IONS IN SAID SOLUTION.
