A particulate oxide composition comprising cerium oxide, trivalent dopant, and optional additional metal oxide, other than cerium oxide and trivalent dopant, is beneficial to aid in the removal of biological contaminants, such as bacteria, viruses, fungi, protozoa (e.g., amoebae), yeast and algae. This particulate oxide composition contains more cerium oxide than trivalent dopant and has a unique depth profile in which the average trivalent dopant to Ce ratio at about 0 nm to about 3.5 nm from the surface of the particulate composition is greater than the trivalent dopant to Ce ratio at about 15 nm from the surface of the particulate composition. These trivalent doped cerium oxide compositions can be used to remove these biological contaminants from fluids, including air and water, and from solid surfaces. Also described are methods of using compositions containing these trivalent doped cerium oxide compositions to remove biological contaminants.

A zirconium polymer composition comprising a zirconium polymer selected from the group consisting of polymeric zirconium oxychloride, polymeric zirconium acetate, and polymeric zirconium nitrate and having metal particles thereon is beneficial to aid in the removal of biological contaminants, such as bacteria, virus, yeast, algae, and amoeba, from fluids, including air and water. In this composition, the metal is selected from the group consisting of aluminum (Al), antimony (Sb), arsenic (As), barium (Ba), silicon (Si), boron (B), copper (Cu), gold (Au), lead (Pb), mercury (Hg), nickel (Ni), silver (Ag), thorium (Th), tin (Sn), zinc (Zn), and mixtures thereof, and the metal particles are about 0.001% by weight to about 30% by weight of the composition. These zirconium polymer compositions are used in methods for removing biological contaminants from fluids.

A cerium (IV) oxide composition having unexpectedly greater arsenic loading capacities than oxides of cerium (IV) of the prior art are disclosed. The arsenic loading capacities are greater at low level equilibrium levels of arsenic. The cerium (IV) oxide composition is more effective at removing arsenite and arsenate. Moreover, the cerium (IV) oxide composition has a greater capacity for the previously more difficult to remove arsenite.

A method for the synthesis of rare earth containing phosphates of the LaPO:Ce,Tb type comprising providing an initial charge of phosphate having a pH above 2 to a reactor; subsequently commencing introduction of a rare earth solution to the reactor, and subsequently, continuing to introduce both the phosphate and the rare earth solution to the reactor to form a mixture; whereby a rare earth phosphate precipitate is produced, at least a portion of which is precipitated while the pH of the mixture is less than 2.
