Synthesis and Analysis of Inorganic Polymers ofCe (IV) - P Compounds.

All of Ce(IV)-pIO compounds can be used as ion exchangc. The solubility of these compounds in inorga nic acids arc vcry low and they can not be formed anionic complexes and can give amorph and crystalize phases under different conditions in which the phosphate gro ups WdS substituted with sulphate groups. The crystal and amorph form of inorga nic polymers of Ce(IV)-P can be prepare from the react ion of orttophos phoric add in the prescnc of Ce(IV)-SYO in H2S04 at 8O-100°C with stirring about 4h. The crystal form of Cc(IY) - P have fibrious strm:turc and ycry simi lar with ceieiuse paper. The X,RD elemental analysis, lR and FTIR and microscopic pictures of polymer under diffrent condition of preparations. and onc of its use as chromatographic separation of inorganic cations was also studied.
