ACTIVE MATERIAL USEFUL AS ADSORBENT COMPRISING METAL OXIDE/HYDROXIDE PARTICLES REACTED WITH ONE OR MORE PHOSPHOROUS-CONTAINING MATERIALS

摘要

An active material is disclosed comprising metal oxide/hydroxide particles having chemically bonded to reactive sites on a surface (50) thereof, a monolayer of a phosphorous-containing organic material comprised of a phosphorous-containing group and a carbon-containing group. The bond to the metal oxide/hydroxide surface (50) is formed by reaction of the phosphorous-containing group with the metal oxide/hydroxide particle surface (50), so that the carbon-containing group of the material is oriented away from the metal oxide/hydroxide surface (50).
