Ceramic nanofiltration membranes for permeation and filtration of organic solutions

摘要：

Silica, titania, and methylated silica membranes having pore sizes in the range of from 1 to several nms were prepared by sol-gel processing, and applied to permeation of hexane as a model nonaqueous solution system. TiO2 membranes, which were suggested to be more hydrophobic than SiO2, were found to show a deceased hexane flux with an increase in water concentration. Negative rejection was observed in nanofiltration of linoleic acid in hexane solution.
