Abstract: The solid complexes of phytic acid with trivalent rare earth metals in aqueoussolution were synthesized and characterized by means of elementary analysis, IRandanalysis.The composition of complexes [(C6H6) H4 (PO4)6]3· RE (Ⅲ)8· C2H5OH· x H2O(x= 10~15, RE = Y, Pr, Gd, Tb, Er, Yb) was determined.The IRspecra of complexesclear polymer.In addition, the thermal cecomposition kinetics of the complexes wass investigatwed as well.

Key words: Rare earth element, Phytic acid, Complexes
