摘要： The problem addressed by the present invention is to provide a method for facilitating the regenerating a waste plating solution as a plating solution. This method for regenerating 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 by removing Fe therefrom 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 a regenerated plating solution.

摘要： A stain removal device and a stain removal method for removing stain, such as scale residue or smut from the surface of a wire material by a cord-shaped member, includes a wire material winding device for winding a wire material on the surface of which the stain is deposited, a cord-shaped member which is wound on the wire material and wipes off stain attached on the surface of a wire material by a sliding movement relative to the wire material, and a cord-shaped member feed device for feeding the cord-shaped member relative to the wire material. The stain removal method includes linear feeding of a wire material, winding a cord-shaped member on the wire material, wiping off the stain attached on the surface of the wire material by rolling up the cord shaped member, and blowing air onto the surface of the wire material to blow away stain remaining thereon.
