Semiconductor manufacturing generates wastewater streams containing valuable transition metal ions such as Cu²⁺. However, selective copper recovery remains challenging due to the presence of competing divalent ions with similar physicochemical properties. This project will develop coordination-regulated polyamide membranes for selective copper recovery from semiconductor wastewater. By tuning the density of carboxylate functional groups within membrane pores, the proposed membranes will leverage coordination interactions to enhance Cu²⁺ selectivity beyond conventional size- and charge-based separation mechanisms. Membrane performance will be evaluated using Cu²⁺, Ni²⁺, and Zn²⁺ transport experiments, and the resulting Cu-enriched streams will be integrated with electrochemical reduction processes for metal recovery. The project will establish a new membrane design strategy based on coordination-regulated ion transport and provide a foundation for sustainable resource recovery and circular water use in semiconductor manufacturing.
