Abstract

Method for continuously measuring small concentrations of chlorides in aqueous solutions, characterized in that it consists of regulating the pH of the water to a neutral or acid value, putting the water in contact with a cationic resin, in the form of H +; in circulating this water, with a regular flow, into a measuring container, in which an Ag-ClAg electrode and a reference electrode are immersed; and in measuring the potential difference between the two electrodes.
