| 摘 要： | 以无机铝盐和氨水为原料,以多通道氧化铝陶瓷为支撑体,采用溶胶 凝胶法制备无缺陷的氧化铝超滤膜。通过自制的实验装置,对所制得的氧化铝超滤膜进行了纯水渗透率、平均孔径、孔径分布和聚乙二醇的截留率 分子量的关系的测试,并用扫描电镜观察了氧化铝超滤膜的表面形貌。结果表明:二次超滤膜的纯水渗透率为1.21m3/m2·h·MPa,平均孔径为11.1nm,聚乙二醇20000的截留率达到92.8%。

| Abstract: | Al_2O_3 ultrafiltration membrane is prepared by sol-gel method with AlCl_3 and NH_3·H_2O as raw materials and with Al_2O_3 ceramics of many passages as supporter. Through the own's pilot plant, water permeability, average pore size, distribution of the pore size, relation of PEG capture and molecular mass of Al_2O_3 ultrafiltration membrane synthesized is measured. Surface of ultrafiltration membranes is observed by SEM. The results showed that water permeability is 1.21 m~3/m~2·h·MPa, average pore size is 11.1 nm,capture rate of PEG 2000 is 92.8% for twice ultrafiltration membrane. |
