Rotating Electrode Technology and Conventional Electroplating Technology share the same electrochemical theoretical foundation. Both involve immersing the anode and cathode in an electrolyte solution containing target metal cations, achieving directed movement of ions under electric fields to deposit the target metal on the cathode.
The difference lies in that rotating electrode devices allow for higher flow velocity of the electrolyte solution, effectively utilizing the rapid flow of the electrolyte to eliminate concentration polarization phenomena during the electroplating process. This ensures more complete reaction and high purity of cathodic products with high current efficiency. It is particularly suitable for (wet metallurgical industry) in the selective electrolysis (electroplating) separation and purification of low-concentration and multi-component electrolyte solutions, or for removing metal ions from wastewater.
