Selective adsorption of Cu, Ni and Zn from steel sludge leachate using polyethyleneimine-functionalized mesoporous hybrid materials in batch and continuous-flow systems.
This study investigates the adsorption properties of amine-functionalized mesoporous organic hybrid materials (μOHMs) for the removal of heavy metals, specifically Cu, Ni and Zn from industrial wastewater streams such as steel sludge. The synthesized microscale (40-60 μm) materials were characterized and evaluated for...
