Synthesis and Characterization of Cerium(IV) Arsenomolybdate Cationic Exchanger

Some trace metals are toxic and their presence in water adds to the accumulation in living organism, causing health problems in human beings, plants and animals [1]. Therefore, it is necessary to remove such metals by using some separation techniques [2]. In an ion-exchange process, the exchange of the ion takes place stoichiometrically between the stationary and mobile phase. The ion-exchange phenomenon was recognized by two Thomson [3] and Ways [4,5] in the soil by the name at base-exchange. An ion exchanger is usually water insoluble solid substance which can take up ions of positive or negative charge from an electrolyte solution in an equivalent amount. There are several requirements for a suitable ionexchanger which are closely interacted. Inorganic ion exchangers [6-8] have drawn considerable attention owing to their high thermal and chemical stability [9]. Many natural and synthetic substances are capable of ion-exchange for technical purposes. However, only those substances which have adequate mechanical and chemical properties are suitable. Three most important groups are detailed within the order of their development: inorganic, natural organic base and synthetic ion-exchangers. Amongst these, the aluminosilicates, both natural and synthetic are suitable for many purposes. Zeolites are naturally occurring cation exchangers. The synthetic ion exchangers fill increasingly the requirements both of laboratories and technology Synthesis and Characterization of Cerium(IV) Arsenomolybdate Cationic Exchanger
