ABSTRACT:
A cellulose/silica composite useful as a filter material is highly selective towards a solute that has been molecularly imprinted upon an inorganic gel coating formed on the cellulose. The filter material provides dual filtering functionality, as both a selective molecular sieve and as a particulate filter. A unique method for making the filter material is also set forth that imparts these attributes and performance capabilities.
