摘要： PROBLEM TO BE SOLVED: To provide a method for recovering lithium, which can be easily industrialized and by which lithium can be selectively and efficiently recovered from a solution containing lithium at a low concentration, such as seawater.SOLUTION: The method for recovering lithium comprises selectively separating and recovering lithium ions from a solution containing lithium ions. By partitioning with a lithium ion selective permeable membrane 5 that is located between an anode electrode 3 and a cathode electrode 4 and is impregnated with an ionic liquid having lithium ion selectivity, a lithium solution cell 8 is formed on the anode electrode 3 side and a lithium ion separation and recovery cell 9 is formed on the cathode electrode 4 side. The solution is supplied to the lithium solution cell 8. Lithium ions permeate the lithium ion selective permeable membrane 5, are dialyzed by the lithium ion separation and recovery cell 9 by electrodialysis method, and thus are recovered.

摘要： PROBLEM TO BE SOLVED: To obtain a CO2 sensor responsive to a relatively low temperature lower than the room temperature and exhibiting high stability for a long term. SOLUTION: Iron (III) is built in a solid electrolyte ceramic 1 having high alkaline ion conductivity. The solid electrolyte ceramic 1 is provided with two electrodes 2, 3 and at least one of them is formed flat and at least partially transparent to CO2 . CO2 sensitivity of the solid electrolyte ceramic 1 is formed by anodic oxidation from iron (III) to iron (IV) and electric polarization for liberating NA ion. In this regard, Na ions touch the air to form a small quantity of Na2 CO3 in the range of the cathode 2. Due to relatively high oxidation/reduction potential of iron (III), the NASICON solid electrolyte ceramic 1 exhibits stability to the small quantity of Na2 CO3 formed by polarization thus realizing a stable CO2 sensor.
