The invention relates to a preparation method of a molecular sieve membrane used for water-removal, comprising processing steps of preparation of the precursor sol of a molecular sieve, hydrothermal crystallization and preparation of the molecular sieve membrane. The molecular sieve membrane prepared by the invention has good hydrophilicity and can be used for pervaporation separation of an organic substance/water under a pervaporation condition so as to realize effective desorption of the water in an organic solvent. In separating isopropanol and the water, the pervaporation separation is carried out in 75 DEG C; when the mass concentration of the water on a feed side is 10 percent, an average flux is 1 to 3kg/m<2>.h; and a separation coefficient reaches 100 to 2000; thereby the invention can be used for desorbing a little water in the organic solvent and preparing an anhydrous reagent.
