ACTIVE MATERIAL USEFUL AS ADSORBENT COMPRISING METAL OXIDE/HYDROXIDE ARTICLES REACTED WITH ONE OR MORE PHOSPHOROUS-CONTAINING MATERIALS HAVING SELECTED ORGANIC RADICALS ATTACHED THERETO

摘要

An active material is disclosed comprising metal oxide/ hydroxide particles having chemically bonded to reactive sites on a surface thereof, a monolayer of a phosphorous-containing organic material comprised of a phosphorous-containing group and a carboncontaining group. The bond to the metal oxide/hydroxide surface is formed by reaction of the phosphorous-containing group with the metal oxide/hydroxide particle surface, so that the carboncontaining group of the material is oriented away from the metal oxide/hydroxide surface.
