Study of effect of two sulfonating agents on electrochemical properties of surface-modified polyethersulfone membrane
Original language description
The work deals with the selection of sulfonating agent and preparation of polymeric coating on membrane step by step. The surface modification of a commercial ultrafiltration polyethersulfone (PES) membrane was covalently attached to the poly(styrene-co-divinylbenzene-co-4-vinylbenzylchloride). The whole process was tracked step by step using analytical methods. Chlorosulfonic acid and trimethylsilyl chlorosulfonate were tested as sulfonating agents. Ion-exchange capacity, water content, specific resistance and permselectivity were measured and scanning electron microscope (SEM) analysed the surface of the cation exchange membrane (CEM). The best results were achieved using 5 wt.% chlorosulfonic acid as sulfonating agent. Ion-exchange capacity (IEC) reached values of up to 2.44 meq g-1 of dry matter, permselectivity of 93.6%, area resistances of 10.1 Ω cm2 and specific resistance around 299 Ω cm. The prepared cation exchange PES membrane with chlorosulfonic acid can be used in electrochemical processes, for example in electrodialysis.
