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.
