Abstract A system for determining the concentration of specific ions in a first aqueous solution wherein a second aqueous solution containing the specific ions is treated in an ion exchanger so that a third aqueous solution having a known concentration of the specific ions emerges therefrom. The first and third aqueous solutions are directed to chambers, respectively, and brought into communication through a diaphragm. A measuring electrode is positioned in the solutions in each chamber and the potential difference between the electrode is measured. In a case where the first aqueous solution is treated in another ion exchanger of the same characteristics as the ion exchanger for the second solution, the potential difference will serve to indicate changes in the behavior of the said another ion exchanger.
A METHOD FOR THE DETERMINATION OF THE CONCENTRATION OF SPECIFIC IONS IN A FIRST AQUEOUS SOLUTION COMPRISING, DIRECTING THE FIRST AQUEOUS SOLUTION CONTAINING THE SPECIFIC IONS TO A FIRST CHAMBER, DIRECTING A SECOND AQUEOUS SOLUTION HAVING THE SPECIFIC IONS IN THE FIRST SOLUTION TO AN ION EXHCANGER, TREATING THE SECOND SOLUTION IN THE ION EXCHANGER AND EXCHANGING THE SPECIFIC IONS OF THE SECOND SOLUTION SUCH THAT A THIRD AQUEOUS SOLUTION HAVING A KNOWN CONCENTRATION OF THE SPECFIC IONS EMERGES FROM THE ION EXCHANGER, DIRECTING THE THIRD AQUEOUS SOLUTION CONTAINING THE KNOWN CONCENTRATION OFTHE SPECIFIC IONS TO A SECOND CHAMBER, BRINGING THE FIRST THIRD AQUEOUS SOLUTION WITHIN THE FIRST AND SECOND CHAMBERS, RESPECTIVELY, INTO COMMUNICATION THUROGH A DIAPHRAGM, POSITIONING A FIRST MEASURING ELECTRODE SENSITIVE TO THE SPECIFIC IONS IN THE AQUE-
