Abstract
PURPOSE: To make possible reuse of Cu2+ for a plating bath by treating the CuSO4 plating waste solution containing respective ions of Cu and Fe with H+ type strong acidic cation exchange resins under sulfuric acid acidic conditions to adsorb both ions then desorbing Fe ions with an oxalic acid solution and further treating the solution with the specific concentration of sulfuric acid.
CONSTITUTION: Cuso4 plating waste solution containing respective ions of Cu and Fe is treated with H+ type strong acidic cation exchange resins unde sulfuric acid acidic conditions of 1N or under to let both ions be adsorbed. Next, the ion exchange resins are treated with an oxalic acid solution of 10 to 100mg/ml, particularly 30 to 50mg/ml to let only the Fe ions be desorbed. Next, the ion exchange resins are treated with a sulfuric acid of 3N or over (preferably 3 to 6N) to recover the eluate containing Cu2+ which is then used for copper sulfate plating solution.
