摘要： Disclosed herein is a reference electrode including an electrolyte containing an optically-active material, including: an electrode body provided at an end thereof with an electrolyte separation membrane and charged therein with an optically-active material and an electrolyte solution; an inner electrode disposed in the electrode body to be immersed in the electrolyte solution; and an absorbance measurement probe for transmitting light to the electrolyte solution and collecting reflected light waves, which is disposed in the electrode body to be immersed in the electrolyte solution. Since the concentration of an electrode reaction material, such as Cl−, in the electrolyte is calculated using the absorbance of the electrolyte solution containing the optically-active material, the change in potential of the reference electrode can be properly corrected even when the reference electrode is exposed to a test environment for a long period of time and thus the concentration of the electrolyte changes. Thus, the functions of the reference electrode can be maintained for a long period of time, thereby rapidly monitoring the abnormal states caused by damage to the reference electrode.

摘要： Disclosed herein is a reference electrode having a self-calibration function, which is used in electrochemical measurement and whose measurement accuracy can be maintained for a long period of time. Also disclosed is an apparatus for automatically correcting electrochemical potential using the reference electrode. The apparatus comprises: a reference electrode, comprising an external electrode body having an electrolyte membrane at one end thereof and an electrolyte solution filled therein, and at least two electrically isolated internal electrodes which are disposed in the external electrode body in such a manner that they are immersed in the electrolyte solution; and a reference potential calibrator for applying AC voltage to the internal electrodes to measure the electrical conductivity of the electrolyte solution of the electrolyte solution and output a correction signal about the change in the reference potential of the reference electrode. The reference electrode and the apparatus can suitably calibrate the change in the potential of the reference electrode by measuring the internal electrolyte of the reference electrode and calculating the concentration of the internal electrolyte, and thus the function of the reference electrode can be maintained for a long period of time.

摘要： Disclosed is a method of in-situ monitoring a reduction process of uranium oxides by lithium metal, wherein a conversion yield of uranium metal from uranium oxides upon production of uranium metal through a reaction of uranium oxides (UOx, x≦3) with lithium metal in the presence of a high-temperature molten salt is measured according to an electrochemical analysis based on an oxidation of an oxygen ion and a reduction of a lithium ion dissociated from lithium oxide obtained as a by-product of the reaction, by use of a measuring device composed of a potentiostat/galvanostat and a reactor provided with an anode and a cathode. The in-situ monitoring method of the current invention is advantageous in terms of fast and simplified measuring techniques, by directly measuring the reduction process of uranium oxides at the anode and cathode connected to the potentiostat/galvanostat in the presence of the high-temperature molten salt.
