Abstract:
  In this work, polyethyleneimine modified multi-walled carbon nanotubes were prepared, polysulfone ultrafiltration membrane, polyethyleneimine and trimesoyl chloride were as the base membrane, water phase monomer, and organic phase monomer, respectively. Modified multi-walled carbon nanotubes were added into the water phase, and the organic-inorganic hybrid composite nanofiltration membrane was prepared by the interfacial polymerization method. The microscopic morphology/chemical properties and dispersion properties of the modified multi-walled carbon nanotubes were analyzed and characterized. The microstructure, infrared spectrum and contact angle of the base membrane and nanofiltration membrane were analyzed and characterized, and the influence of the addition amount of polyethyleneimine modified multi-walled carbon nanotubes on the membrane performance was discussed. The results show that the water flux of the composite nanofiltration membrane with 100mg·L-1 modified multi-walled carbon nanotubes can reach 11.95L·m−2·h−1·bar−1, and the rejection rate of MgCl2 is 94.4%. At the same time, the rejection rate for the four common commercial dyes is about 98%.
