Abstract

PROCEDE POUR LA DETERMINATION COULOMETRIQUE DE LA TENEUR D'UN COMPOSANT DISSOUS DANS L'EAU, PAR EXEMPLE L'OXYGENE GAZEUX DANS L'EAU DE MER, ET CELLULE COULOMETRIQUE POUR LA MISE EN OEUVRE DE CE PROCEDE. LA CELLULE COMPREND UNE CELLULE DE MESURE CENTRALE ALLONGEE 1 ET DEUX CELLULES AUXILIAIRES 2 RACCORDEES DIRECTEMENT A CHAQUE EXTREMITE DE LA CELLULE DE MESURE 1. L'ELECTROLYSE EST EFFECTUEE SIMULTANEMENT DANS LA CELLULE DE MESURE 1 ET LES CELLULES AUXILIAIRES 2 DANS DES CONDITIONS CALCULEES DE TELLE SORTE QUE LA CONCENTRATION DU COMPOSANT DISSOUS DIMINUE AU MEME RYTHME DANS LES TROIS CELLULES.
