Abstract:
 Amino-modified mesoporous silica (AMMS) was successfully prepared by using sol-gel reaction and was then blended with SPPO solution to prepare organic-inorganic hybrid membranes. The performance of the membranes were investigated in NaOH/Na2WO4 model system for alkali recovery via diffusion dialysis (DD), and the results showed that the introduction of mesoporous silica could solve the "trade-off" effect to a certain extent in the membrane separation process: the ion flux of the hybrid membrane was higher than that of the pure SPPO membrane, and the separation factor was also maintained at a higher level. After exploring the mass transfer mechanism, it was believed that the mesopores and -NH2 on the surface of mesoporous silica played an important role in ion transport.
