Method for managing electrodeposition liquid, and electrodeposition device

Abstract

A method for managing an electrodeposition dispersion is used in a case where an electrodeposition film is formed on a substrate having conductive properties by anionic electrodeposition, and the method includes: adjusting a concentration of an organic acid contained in the electrodeposition dispersion by subjecting the electrodeposition dispersion to an anion exchange treatment. An electrodeposition device is used in a case where an electrodeposition film is formed on a substrate having conductive properties by anionic electrodeposition, and the electrodeposition device includes: an electrodeposition tank in which an electrodeposition dispersion is stored and a substrate and a counter-electrode are immersed; an anion exchange means for subjecting the electrodeposition dispersion to an anion exchange treatment; and an electrodeposition dispersion circulation means for circulating the electrodeposition dispersion between the electrodeposition tank and the anion exchange means.
