METHOD OF ANALYZING PLATING SOLUTION AND METHOD OF PRODUCING METALLIC BODY

摘要

PROBLEM TO BE SOLVED: To provide a method of analyzing a plating solution which is used to detect a change of the dissolve oxygen content of a plating solution for deposition of a metal lower in standard electrode potential than water.SOLUTION: A method of analyzing a plating solution includes a step of applying a negative potential, relative to the standard electrode potential of an object metal, to an electrode in a plating solution consisting of a nonaqueous electrolyte to cause the object metal to be deposited on the surface of the electrode and a step of applying a positive potential, relative to the standard electrode potential of the object metal, to the electrode for a time longer than the time for application of the negative potential to dissolve the object metal on the surface of the electrode, and a dissolved oxygen content in the plating solution is calculated on the basis of a ratio of the dissolved amount to the deposition amount of the object metal.
