Title:
METHOD AND APPARATUS FOR REGENERATING ALUMINUM ANODIC OXIDATION FILM PORE-SEALING TREATMENT LIQUID
Document Type and Number:
Japanese Patent JP2014173152
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide, as a method for regenerating a pore-sealing treatment liquid including lithium ions and having been used for a pore-sealing treatment of an aluminum anodic oxidation film, a method capable of efficiently removing aluminum from the pore-sealing treatment liquid.SOLUTION: A pore-sealing treatment liquid is contacted with a chelate resin including aminophosphoric acid as a functional group so as to induce the adsorption, on the chelate resin, of the aluminum component within the pore-sealing treatment liquid and to abate the aluminum concentration within the pore-sealing treatment liquid. It is desirable for the ion form of the chelate resin to be a lithium ion form.
