ABSTRACT:
An ion exchange material comprises an oxide of a first element selected from elements of Groups IVa, IVb, Va, Vb, VIa, VIb, VIIa, or lanthanide or actinide series of the Periodic Table, in combination with an oxide of at least one different element selected from elements of the afore-mentioned groups of the Periodic Table so as to form a composite material. For example, a composite ion exchange material may comprise silicon dioxide and manganese dioxide. By selecting the appropriate oxides a composite ion exchange material can be prepared which has greater mechanical and/or chemical stability than an individual oxide of the composite material.
