Abstract:
1. An adsorbent filter material useful for removing a solute from a fluid, comprising: a liquid permeable fibrous support material comprising fibers having hydroxyl groups, hydrolyzable alkoxyl groups, amino groups, or sulfhydryl groups; and an adsorbent porous inorganic gel coating on the fibrous support material, wherein the inorganic gel coating has been molecularly imprinted for the solute using template molecules present during formation of the inorganic gel coating but selectively removed thereafter from the filter material, wherein the fibrous support material comprises cellulose having a lignin content of less than 1.0 percent, the support material having been surface treated sufficiently so as to maintain attachment of the gel coating to the support material, without leaching off of the support material, upon contact with water at about 100 degrees C.
