The controller is electrically connected, the device also includes a purification tank, the electrolytic tank is provided with an overflow port connected to the purification tank, the purification tank is provided with a water outlet, and the water outlet is connected to the electroplating tank; the impurity removal method The method includes an electrolytic impurity removal step and an impurity recovery step, and has the characteristics of simple operation and good impurity removal effect.

Description

technical field [0001] The invention relates to the technical field of impurity removal in electroplating solution, in particular to an electrolytic column for electrolytic removal of impurities in nickel plating solution, an electrolytic removal of impurities and a method for removing impurities. Background technique [0002] In the electroplating nickel process, whether it is electroplating dark nickel, semi-gloss nickel, or bright nickel, satin nickel and other plating types, some metal impurities such as copper, lead, iron, zinc, etc. will be brought in, and the content of impurities in the nickel plating solution is It will directly affect the quality and stability of the coating, especially copper ions, which directly affect the brightness and compactness of the coating, so it is particularly important to remove impurities from the nickel plating solution. Existing impurity removal methods for nickel plating solution include chemical impurity removal method and electro...
