技術摘要:
Integrally skinned asymmetric flat-sheet imidazole-based membranes were fabricated using the nonsolvent-induced phase separation (NIPS) method under various pH in a coagulant bath. The effects of acidity and alkalinity of the nonsolvent during the phase inversion process on membrane formation and NF performance were systematically investigated. The membrane formed under pH 12 and modified through the surface coating method has a molecular weight cut-off (MWCO) as low as 288 Da and an MgCl2 rejection of more than 97%. The membrane also displays pH-responsive characteristics for salt separation with unequal valence ratios of co-ions and counter-ions. It is able to show a competitive S(Li, Mg) value for Li+/Mg2+ separation surpassing the state-of-the-art performance of commercial membranes.
