Surface-modified adsorbent comprising metal oxide/hydroxide particles reacted with one or more perfluorinated organic acids |
摘要 |
An active material and method of making same are disclosed comprising a metal oxide/hydroxide surface having chemically bonded to reactive sites thereon, a layer of a perfluorinated organic material formed by reacting with the metal oxide/hydroxide a perfluorinated organic acid comprised of an acid group and a perfluorinated carbon-containing group. The bond to the metal oxide/hydroxide surface is formed by reaction of the acid group with the metal oxide/hydroxide surface, so that the perfluorinated carbon-containing group is oriented away from the metal oxide/hydroxide surface. The perfluorinated organic acid may be a perfluorinated phosphonic acid, a perfluorinated phosphinic acid, a perfluorinated carboxylic acid, or a mixture of two or more of the acids.
