摘要： A novel and efficient electrochemical method is disclosed for the recovery of lithium value from an aqueous solution containing lithium ions in a relatively low concentration together with ions of various kinds of other metallic impurity elements. The method comprises electrochemical selective adsorption of lithium ions from the aqueous solution on to a specific working electrode by applying a DC voltage of a relatively low DC voltage of 0.1-0.4 volt versus a saturated calomel electrode to the working electrode as the cathode opposed to a counterelectrode as the anode and then desorption of the lithium ions therefrom by applying a DC voltage of 0.7-1.2 volts versus a saturated calomel electrode to the lithium-bearing working electrode as the anode opposed to a counterelectrode as the cathode in an aqueous desorption medium containing an electrolyte such as a lithium salt. At least the surface layer of the working electrode is formed from an oxide of manganese prepared by admixing a manganese compound with a limited amount of a lithium or magnesium compound, converting the mixture into oxides by a heat treatment in an oxidizing atmosphere and then removing the lithium or magnesium therefrom by leaching in an acid solution or by an electrochemical means.

摘要： A highly sensitive and reliable electrochemical method is proposed for the determination of the lithium ion concentration in an aqueous medium, e.g., blood of a patient suffering depression and administrated with a lithium-containing medicament, by measuring the electromotive force between the medium and a powdery non-selective electrode, which is a non-stoichiometric composite oxide of lithium and manganese of the formula Li.sub.x Mn.sub.2 O.sub.4, x being a positive number smaller than 1, prepared by partially leaching lithium ions out of a spinel-type lithium manganate LiMn.sub.2 O.sub.4 with an acid, dipped in the medium. The ion-selective electrode can be in the form of a thin film or coating layer on an electrode element. This film or layer can be formed of a polymeric resin as a binder for the powdery composite oxide.
