Abstract

See full text

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.
