This study focuses on the kinetic process of recovering Cu²⁺ from electroplating sludge in the form of elemental copper using bipolar membrane electrodialysis （BMED） coupled with electrodeposition technology， aiming to provide a theoretical foundation for optimizing the process conditions. The research investigated the effects of sludge pH on Cu²⁺ desorption and BMED current density on Cu²⁺ migration， as well as the influence of current density， solution pH， and initial Cu²⁺ concentration on the Cu²⁺ electrodeposition rate in the electrodeposition system. The processes of Cu²⁺ desorption and migration were analyzed using Elovich equation， double constant equation， pseudo-first-order kinetic equation， pseudo-second-order kinetic equation and parabolic equation， and the electrodeposition process was further analyzed by pseudo-first-order and pseudo-second-order kinetic models. The results show that：（1）Sludge pH significantly impacts Cu²⁺ desorption， and the desorption kinetics conforms to Elovich equation， double constant equation， and pseudo-second-order kinetic models. The BMED current density significantly influences the Cu²⁺ migration， and the migration process conforms to Elovich equation， double constant equation， and parabolic equation. The current density， solution pH and initial Cu²⁺ concentration in the electrodeposition system have significant effects on the electrodeposition rate of Cu²⁺， and the process accords with the pseudo-first-order kinetic model. （2）Under the optimal experimental conditions， 85.7% of Cu²⁺ in the electroplating sludge was transferred to the BMED recovery chamber， and 65.4% of Cu²⁺ was recovered as copper foil with a purity of 99.8%. These findings demonstrate that BMED coupled with electrodeposition technology is highly effective for recovering Cu²⁺ from electroplating sludge in the form of elemental copper. This study also reveales the migration and electro-deposition kinetics of Cu²⁺， providing a feasible technical path and theoretical foundation for optimizing the resource utilization of electroplating sludge， which has important environmental and economic value.
