Abstract: The ceric and cerous solid complexes with phytic acid were synthesized and chara cterized by means of elemental analysis, IR and TG-DTA. The results show that under the experimental conditions for Ce(Ⅲ)only one form complex is formed:[(C6H6)H4(PO4)6]3Ce8·13H2O(Ⅰ), but two complexes were formed for Ce(Ⅳ):[(C6H6)H4(PO4)6]3·Ce8·9H2O(Ⅱ)and [(C6H6)(PO4)6]3[Ce(OH)]12·9H2O(Ⅲ); the thermal stability of(Ⅲ)was less than that of(Ⅰ). On thermal decomposition the ceric was reduced to cerous and the final product was CePO4.
Key words: ceric, cerous, phytic acid, solid complex
