摘要

Abstract

A novel composite charged mosaic membrane (CCMM) was prepared via interfacial polymerization (IP) of polyamine[poly (epichlorohydrin amine)

]

and trimesoyl chloride (TMC) on the polyethersulfone (PES) support. Fourier transform infrared spectroscopy (FT-IR)

environmental scanning electron microscopy (ESEM)

atomic force microscopy (AFM) and water contact angle analysis were applied to characterize the resulted CCMM.The FT-IR spectrum indicates that TMC reacts sufficiently with polyamine.ESEM and AFM pictures show that the IP process produces a dense selective layer on the support membrane.The water contact angle of the CCMM is smaller than that of the substrate membrane because of the cross-linked hydrophilic polyamine network.Several factors affecting the IP reaction and the performance of the CCMM

such as monomer concentration

reaction time

pH value of aqueous phase solution and post-treatment

were studied.The pure water flux of the optimized CCMM is 14.73 L·m

at the operating pressure of 0.4 MPa.The values of separation factorαfor NaCl/PEG1000/water and MgC

/PEG1000/water are 11.89 and 9.96

respectively.These results demonstrate that CCMM is promising for the separation of low-molecular-weight organics from their salt aqueous solutions.
