Abstract:
 On the basis of polyethyleneimine (PEI)/sodium lignosulphonate (SL) nanofiltration membranes, graphene oxide (GO) modified PEI/SL nanofiltration membranes were prepared through layer-by-layer assembly technology. The characterizations, such as ATR-FTIR, XPS, SEM, have be used to study the influence of GO on the structure of the composite membrane. The results show that the self-assembly process can successfully prepare GO modified PEI/SL membranes, in which the GO sheets are incorporated in the PEI/SL layer. It is also found that the GO distributes better in PEI than that in SL. Then the nanofiltration performance, tested by using 2 g/L MgSO4 solution at the operating pressure of 1.0 MPa, indicates that the separation performance is improved when 0.025 g/L to 0.035 g/L GO dispersed in the PEI solution or 0.015 g/L to 0.025 g/L GO dispersed in SL solution. The optimal membrane exhibits the rejection reaching 90%, which is 19% higher than the PEI/SL membrane. In this paper, the GO modified nanofiltration membrane prepared by layer-by-layer self-assembly method can be provide a reference for the improvement in nanofiltration performance.
