摘要
将Zr-MOF添加到均苯三甲酰氯的正己烷溶液(有机相)中,采用界面聚合法制备出Zr-MOF改性聚酰胺复合膜。研究了添加物Zr-MOF的浓度和膜的朝向对复合膜正渗透性能的影响。用傅立叶红外光谱(FTIR)、扫描电子显微镜(SEM)、接触角测量仪对所得正渗透复合膜进行分析表征,用1mol/L的氯化钠水溶液为汲取液、去离子水为原料液进行分离性能测试。研究发现,Zr-MOF在有机相中的添加量为0.06%时,正渗透复合膜朝向原料液(AL-FS)的水通量从2.60L/(m2·h)增加到6.98L/(m2·h);朝向汲取液(AL-DS)的水通量从5.58L/(m2·h)增加到13.60L/(m2·h)。
Zr-MOF incorporated thin-film composite membrane for forward osmosis was fabricated by forming polyamide layer on the substrate via interfacial polymerization（IP）with 1,3,5-benzenetricarbonyl trichloride hexane solution containing MOF.The effects of Zr-MOF concentration and membrane orientation on the performance of forward osmosis membrane were studied prevailingly.FT-IR,SEM,and contact angle have been utilized to characterize the thin-film nanocomposite membrane for forward osmosis.With a 1mol/L NaCl as draw solution and DI water as feed solution,the water flux of TFN0.06 membrane prepared with dispersing 0.06wt% of Zr-MOF in the organic phase,reached from 2.60 to 6.98L/（m2·h）and 5.58 to 13.60L/（m2·h）with the active layer faced to feed solution（AL-FS）and draw solution（AL-DS）,respectively.The results are over two times higher than the pure polyamide TFC membrane.
