采用前驱体膜法制备高渗透陶瓷微滤膜。通过在氧化铝微滤膜前体膜中添加勃姆石溶胶，改善了氧化铝微滤膜的性能。随着勃姆石溶胶含量的增加，膜的有效平均孔径不断减小，膜的分离效率不断提高。这是由于勃姆石溶胶不仅有利于α-Al 2 O3粉体在成膜浆料中的分散，而且在α-Al 2 O3颗粒之间的空隙中形成γ-Al 2 O3，有利于膜的烧结和孔径的减小。对于用45wt%勃姆石溶胶制备的膜，有效平均过滤孔径为178 nm，并且膜的水渗透性达到1691 Lm-2 h-1bar-1，这比之前报道的值好得多。此外，使用回收测试确认膜的可重复使用性。
Precursor film method was used to prepare highly permeable ceramic microfiltration membranes in this work. The performance of alumina microfiltration membranes was improved by adding boehmite sol in the membrane precursor film. With increasing the boehmite sol content, the effective average pore size of the membrane was continuously decreased and the separation efficiency of the membrane was increased. These improvements were due to that the boehmite sol not only helped the dispersion of the α-Al2O3powder in the membrane forming slurry, but also formed γ-Al2O3in the gaps among the existed α-Al2O3particles which was beneficial for membrane sintering and pore size decreasing. For the membrane prepared with 45 wt% boehmite sol, the effective average filtration pore diameter was 178 nm and the water permeance of the membrane reached 1691 Lm−2h−1bar−1, which was much better than the values reported before. Moreover, the reusability of the membrane was confirmed using a recycling test.
