Abstract：

Sulfonated poly ether ether ketone (SPEEK) was obtained by sulfonating poly ether ether ketone (PEEK) with concentrated sulfuric acid, and rod-shaped mesoporous silica (MS) was successfully synthesized by modified Stöber method. A series of SPEEK/MS composite membranes were prepared by blending MS suspension and SPEEK solution directly. The basic properties and microscopic structures of as-prepared membranes were measured. The separation performance of the composite membranes were tested by the diffusion dialysis process of NaOH/Na2WO4 system. And results showed that the composite membrane possessed the optimal separation factor of 34.7 while the addition of MS was 4%, which was higher than that of pure SPEEK membrane (13.6). This confirmed that incorporation of MS could significantly improve the selectivity of the composite membranes and prevent the transport of the WO42- ions.
