Abstract：

By the way of dipping-thermal decomposition, positively charged microporous ceramic membrane was prepared in this study which selected microporous diatomite as based-membrane and nano-Y2O3 as charged agent. Nano-Y2O3 was synthesized through the reaction of YCl3 and NaOH. The composition and structure of charged membrane was characterized by TGA、XRD、SEM、EDS、Zeta potential and so on. These results indicated that the precursor completely transformed into nano- Y2O3 with average particle size 118nm when calcined at 700℃. The crystal of Nano-Y2O3 grew well. Pore structure of charged membrane kept fine. And nano-Y2O3 attached uniformly on the membrane surface. In the pH range of 4~8, charged membrane with an isoelectric point of 8.11 possessed strongly positive electricity. The positive performance of charged membrane predicts a great application prospect in terms of removing negative charged microorganism, bacteria, viruses and organic dyes and so on.
