The invention provides a method for preparing
metal-organic framework UiO-66 series membranes and separating a
methanol / methyl tert-butyl
ether mixture and belongs to the technical field of
chemical separation. According to the method, the
metal-organic framework UiO-66 series membranes are growth and synthesized through putting a porous
ceramic tube carrier with a seed layer into a membrane forming solution; through adding a glacial
acetic acid regulator, the forming of continuous and complete high-performance membranes is facilitated. The
methanol / methyl tert-butyl
ether mixture is effectively separated by using the screening performance and
methanol preferential adsorbability of the UiO-66 series membranes, and the UiO-66 series membranes have good stability in a
separation system. According to the method, by making full use of the screening performance and methanol
preferential adsorption characteristic of the UiO-66 series membranes, the
permeation flux is relatively high and is higher than 1.2kg / (m<2>h), the separation effect is good, the separating factor is greater than 200, and the
permeation performance can be kept stable in long-term operation, so that the practical application value is potential.
