dc.description.abstractEFFECT OF CONCENTRATION OF SULFONATING AGENT ON THE CHARGE EFFECTIVENESS OF SULFONATED POLYSULFONE MEMBRANE. Polysulfone (PSF) has been sulfonated homogeneously using chlorosulfonic acid as a sulfonating agent in chloroform. The concentration of sulfonating agent from 6 to 10 wt%was varied to study its effect on membrane effective charge. The sulfonatedmembranewere characterizedto determinethe presence of functional group by Fourier Transform-Infra Red (FT-IR), the Ionic Exchange Capacity (IEC) by titration, the water uptake by gravimetry and the transport properties by membrane potential measurements. It was found a new peak at 3350 em:' after sulfonation, which corresponds to -OH stretching of the sulfonicgroup. This data proved that the -SOJH group were introducedsuccessfullyinto the polymer chain. Based on Teorell-Meyer-Sievers(TMS) equation and membranepotential data, we found that the membrane effective charge increases with the sulfonating agent concentration. The increase of concentration from 6 to 8 wt% increases the effective charge from 0.003 to 0.06. This result was also supported by lEC and water uptake data.en_US
