Hyperbranched poly(amidoamine)/polysulfone composite membranes for Cd(II) removal from water

► Hyperbranched poly(amidoamine) (HYPAM) were combined to an PSf membrane by phase inversion process. ► HYPAM/PSf membrane yielded high recovery efficiencies as well as binding capacities toward heavy metal ions. ► The resultant material was applied as efficient recoverable and reusable membrane for heavy metal ion removal.
