Document Type and Number:
WIPO Patent Application WO/2014/122726
Kind Code:
A1
Abstract:
The problem addressed by the present invention is to provide a method for facilitating the regenerating of a plating solution from a waste plating solution. This method for regenerating plating solution by removing Fe from an acidic waste plating solution containing as ions Fe and at least one plating metal element selected from the group consisting of Cu, Ni, Zn, Co, and Mn is characterized in having an addition step in which phytic acid is added to the waste plating solution to yield a phytic-acid-containing solution in which Fe ions are precipitated, and a removal step in which the precipitate is removed from the phytic-acid-containing solution to yield regenerated plating solution.
