## Abstract A new method to introduce iminodiacetic acid (IDA) onto polyethersulfone (PES) matrix through chlorosulfonation was described in this work, and the prepared PESβIDA was used as adsorbent for the removal of metal ions from aqueous solutions. Chlorosulfonic groups (ο£ΏSO~2~Cl) were introduc
A novel derivative of aromatic polyethersulfone (PES) was obtained by bromination. Victrex PES was reacted with bromine under various conditions: in solution, in suspension, and without solvent; with or without catalyst; and at low and elevated temperatures. Practically no bromination occurred in so
Polyethersulfone (PES) ultrafiltration membranes were modified by radical grafting with the aid of redox initiators to create new functional groups on the surface. Methacrylate-based monomers were used. The modified membrane surfaces were characterized by FTIR-ATR spectroscopy to detect chemical cha
