摘　　要：文章针对MFI分子筛膜的微波法制备和分子筛膜的反渗透脱盐开展研究。传统二次生长法制备MFI分子筛膜需要12 h以上,改进的微波二次生长法制备分子筛膜仅需2 h,提高了制膜效率。制备的MFI分子筛膜可以应用于0.1 mol/L Na Cl的反渗透实验,水通量0.13 kg/m2·h,Na+截留率超过75%。MFI zeolite membrane was synthesized with microwave. Traditional secondary growth method needed more than 12 hours, while improved microwave secondary growth method needed only 2 hours. The efficiency of MFI zeolite membrane preparation was obviously enhanced. The MFI zeolite membrane prepared could be used in reverse osmosis desalination for the 0. 1 M NaC1 solution, with the water flux 0.13 kg·m-2 · h-1 and Na＋ reiection more than 75%.
