湿化学法制备多通道ZrO2超滤膜
Preparation of multichannel Zr02 ultrafilration membrane with suspension derived from wet chemical synthesis
摘要
Abstract
Zirconia ultrafiltration membranes were fabricated by the wet chemical route.The multichannel zirconia mierofiltration membrane with the pore size of 200 nm served as the substrate, and zireonia nanoparticle suspension was used to form the membrane layer.The effects of sintering temperature on the microstrueture were investigated by X-ray diffraction (XRD) analysis and nitrogen adsorption/desorption.The morphology of the membrane was analyzed by scanning electron microscope (SEM).The permeation and separation performances of the membranes were evaluated by cross-section filtration.The results showed that the membranes were crack-free when the sintering temperature was controlled at 600 ℃.The membrane had higher pure water flux and the molecular weight cut off (MWCO) was 20 000 for multichannel zirconia membrane.The retention rate of the egg albumin (Mw =43 000) reached 95％.关键词
