以聚乙二醇400为致孔剂，制备了羧基多壁碳纳米管/海藻酸钙（CMWCNT/CA）复合水凝胶纳滤膜。采用扫描电镜、透射电镜、红外光谱对膜进行了表征，并对膜的强度、抗污染性能和染料截留率进行了研究。结果表明，CMWCNT/CA膜的拉伸强度高达1.83MPa。牛血清白蛋白（BSA）溶液的通量为纯水通量的96.87%，表明膜具有良好的抗污染性能。在饱和吸附后，对刚果红的截留率仍达98.62%。(C)2015 Elsevier B. V.版权所有。
Carboxyl multi-walled carbon nanotubes/calcium alginate (CMWCNT/CA) composite hydrogel nano-filtration membrane was prepared using polyethylene glycol 400 as the pore-forming agent. The membrane was characterized by SEM, TEM and FT-IR. And the strength, anti-fouling property and dye rejection were investigated. Results showed that the CMWCNT/CA membrane had a high tensile strength up to 1.83 MPa. The flux of bovine serum albumin (BSA) solution was 96.87% of the pure water flux (PWF), indicating that the membrane exhibited good anti-fouling property. Even after the saturated adsorption, the rejection for Congo red still reached 98.62%. (C) 2015 Elsevier B.V. All rights reserved.
