摘要： A monitoring method of metal ions or oxygen ions applicable to a high concentration non-aqueous electrolyte includes: applying a potential in a non-aqueous electrolyte to obtain current information with respect to the potential; varying the potential applied in the non-aqueous electrolyte containing metal ion concentration or oxygen ion concentration such that the metal ion concentration or the oxygen ion concentration is maintained in spite of the potential being applied; detecting a linear relationship among the concentration, the current, and passed charges in the non-aqueous electrolyte by repeatedly performing the obtaining step and the varying step, while changing the concentration; and calculating metal ion concentration or oxygen ion concentration of the non-aqueous electrolyte in pyroprocessing of the non-aqueous electrolyte by using the linear relationship. Concentration and components of a solute existing in a non-aqueous electrolyte can be measured while an electrowinning process and pyroprocessing is being conducted.

摘要： A a process as well as an immersion sensor for measuring an electrochemical activity of a layer lying on a melt is provided, using an electrochemical sensor, which has a measuring cell and a counter electrode. In order to make possible reliably reproducible and accurate measurements in the layer, the measuring cell and counter electrode are first immersed in the melt, wherein the measuring cell and counter electrode are protected from contact with the layer and wherein the measuring cell and counter electrode are brought into contact with the melt and are heated. After that, the measuring cell is pulled up to perform the measurement in the layer, wherein the counter electrode is located in the melt during the measurement. For this purpose, the measuring cell and the counter electrode have a protective cover, and the measuring cell is arranged, in the immersion position of the sensor, above the counter electrode.
