THE METHOD FOR MEASUREMENT OF LITHIUM METAL IN THE METAL REDUCED AFTER ELECTROCHEMICAL REDUCTION

摘要

The present invention relates to a quantitative measuring method of lithium which remains in metal diverters. The method comprises the steps of: (a) dipping inner and outer mesh structures which contain a metallic oxide inside into LiCl molten salt; (b) dipping a metal diverter including remaining lithium after electrolytic reduction into LiCl molten salt; (c) returning the metallic oxide into metal through the reaction between the metallic oxide and metal diverter; and (d) analyzing the metal returning rate of a metallic oxide after a return. The quantitative measuring method of lithium which remains in metal diverters in the present invention is capable of decreasing inconvenience of extracting a metal diverter under Argon atmosphere to the air and returning the same back to water, reducing the amount of radioactive liquid waste accumulated by discharged waste water, and significantly reducing measurement errors because it is not about a method of measuring gas generated.
