Ion-Selective Membranes for the Recovery of Nickel

Ion-selective membranes are developed for recovery and recycling of nickel from industrial process streams and wastewaters, addressing critical material supply chain objectives. The research examines membrane selectivity and transport mechanisms for nickel ion separation in complex solution matrices representative of stainless steel, superalloy, and battery manufacturing effluents. Performance data support the viability of membrane-based nickel recovery as a complement to conventional hydrometallurgical processes.
