Enhanced adsorption of Cu(<scp>ii</scp>) ions on chitosan microspheres functionalized with polyethylenimine-conjugated poly(glycidyl methacrylate) brushes

Abstract

Crosslinked chitosan microspheres were tethered with branched polyethylenimine-conjugated poly(glycidyl methacrylate) brushes<italic>via</italic>surface-initiated ATRP and were further utilized as novel adsorbent to purify Cu(<sc>ii</sc>)-contaminated aqueous solution​.
