Title (EN) A PROCESS AND A MEASURING CELL FOR THE COULOMETRIC DETERMINATION OF THE CONTENT OF A COMPONENT DISSOLVED IN WATER
(FR) PROCEDE DE DETERMINATION COULOMETRIQUE DE LA TENEUR D"UN COMPOSE EN SOLUTION AQUEUSE
Abstract:
(EN) A process for the coulometric determination of the content of a component dissolved in water, e.g. oxygen gas in sea-water, and a coulometer cell for carrying out said process. The cell consists of an elongated central measuring cell (1) and two auxiliary cells (2) which are directly connected to each end of the measuring cell (1). Electrolysis is performed simultaneously in the measuring cell (1) and the auxiliary cells (2) under such conditions that the concentration of the dissolved component will decrease at the same rate in all there cell elements.
(FR) Procede de determination coulometrique de la teneur d"un compose en solution aqueuse, par exemple, du gaz oxygene dans de l"eau de mer, et cellule coulometrique pour l"application de ce procede. La cellule comprend une cellule centrale de mesure, allongee (1) et deux cellules auxiliaires (2) directement connectees a chaque extremite de la cellule de mesure (1). L"electrolyse a lieu simultanement dans la cellule de mesure (1) et dans le cellules auxiliaires (2) dans des conditions telles que la concentration du compose dissout decroit selon un taux identique dans les trois cellules.
