Abstract

A.L'INVENTION CONCERNE UN PROCEDE DE MESURE OU DE REGULATION DANS DES OPERATIONS CHIMIQUES PAR DETERMINATION DE LA CONCENTRATION D'IONS A L'AIDE D'UNE ELECTRODE SENSIBLE AUX IONS ET AU POTENTIEL REDOX. B.ON DERIVE UN COURANT PARTIEL DU SYSTEME QUI DOIT ETRE MESURE ET EXECUTE LA MESURE EN DETERMINANT CHAQUE FOIS LE POINT ZERO PAR TRANSFORMATION TOTALE DU TYPE D'ION AVEC UN REACTIF APPROPRIE, APRES AVOIR DETERMINE LA CONCENTRATION MOMENTANEE DES IONS RECHERCHES PAR DES MESURES POTENTIOMETRIQUES. C.CE PROCEDE PERMET DE COMPENSER LES MODIFICATIONS DU POINT ZERO, QUAND IL RISQUE DE SE DEPLACER SOUS L'EFFET D'IONS PERTURBATEURS.A. THE INVENTION RELATES TO A MEASUREMENT OR REGULATION PROCESS IN CHEMICAL OPERATIONS BY DETERMINATION OF THE CONCENTRATION OF IONS USING AN ELECTRODE SENSITIVE TO IONS AND TO REDOX POTENTIAL. B. A PARTIAL CURRENT IS DERIVED FROM THE SYSTEM WHICH MUST BE MEASURED AND CARRIED OUT THE MEASUREMENT BY DETERMINING EACH TIME THE ZERO POINT BY TOTAL TRANSFORMATION OF THE TYPE OF ION WITH AN APPROPRIATE REAGENT, AFTER HAVING DETERMINED THE MOMENTARY CONCENTRATION OF THE IONS SOUGHT BY SCORED MEASUREMENTS . C. THIS PROCESS ALLOWS TO COMPENSATE FOR ZERO POINT MODIFICATIONS WHEN IT IS LIKELY TO MOVE UNDER THE EFFECT OF DISRUPTIVE IONS.
