摘　　要：铈（Ⅲ）、铈（Ⅳ）与植酸生成的固态配合物的研究黎晓霞杨瑛＊刘建民杨汝栋（兰州大学化学系兰州７３００００）关键词铈（Ⅲ），铈（Ⅳ），植酸，固态配合物１９９６－１１－２０收稿，１９９７－０５－２６修回植酸（Ｈ１２ＩＨＰ）作为沉淀剂已被用于Ｔｈ４＋的定量测...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:[(C6H6)H4(PO4)6]3Ce8·13H2O(Ⅰ), but two complexes were formed for Ce(Ⅳ):[(C6H6)H4(PO4)6]3·8·9H2O(Ⅱ) and [(C6H6)(PO4)6]312·9H2O(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 CePO4.
