Polymerization Method

Hollow fiber composite nanofiltration (NF) membranes were prepared by interfacial polymerization method, with polysulfone (PSF) hollow fiber ultrafiltration membrane as base membrane, piperazine (PIP) as the aqueous phase monomer and trimesoyl chloride (TMC) as the organic phase monomer. The effects of aqueous phase composition on composite NF were discussed. The experimental results show that the optimum compositions in aqueous phase: 1wt% PIP, 0.05wt% MPDA, 1wt% TEA, 3wt% sulfamic acid. The best rejection to MgSO4 was 94.7%, and water flux was 66.1L•m-2•h-1.

Thin-film nanofiltration composite (TFNFC) membrane consisting of polyethersulfone (PES) nanofibrous support layer modified by 3, 4-dihydroxy-phenethylamine (dopamine) and interfacial polymerization (IFP) polyamide selective barrier layer was obtained in this study. The hydrophilicity of PES nanofibrous membrane was tremendously improved as the water static contact angle changed from 81.6° to 26.83° by dopamine modification. An ultrathin selective layer was produced by IFP reaction between solutions of piperazine (PIP) and trimesoyl chloride (TMC) on the dopamine modified porous PES membrane. The TFNFC membrane presented relatively high permeate flux (~59.9 L/m2h) and high salt rejection (~98.9%) to divalent anion solutions (1000mg/L, Na2SO4) at a low pressure of 0.6 MPa. It could be believed that dopamine modification would be very efficient to fabricate the composite membranes with stable structure and high filtration performance.
