摘要：
A chromatographic packing material is disclosed which comprises generally spherical metal oxide/hydroxide support particles comprising crystals extending radially outward from a central core region and having a shape selected from principally acicular to principally lamellar and having bonded to the surface of said metal oxide/hydroxide support particles a layer of one or more phosphorus-containing organic materials comprised of a phosphorus-containing acid group bonded to said metal oxide/hydroxide particles and an unreacted carbon-containing acid group.
