The mono substituted tungstoferrate containing Ni Ⅱ、Co Ⅱ、Cu Ⅱ、Zn Ⅱ,K 7[FeW 11 O 39 Z(H 2O)]·xH 2O,were synthesized and characterized by elemental analysis UV IR spectrometry,polarogram and ESR.The results show that the ν w-O d λ of O b/O c→W absorption peak and first half wave potentials of FeW 11 Z are regularly changed with substituted atom Z, owing to the structural nature of heteropolyanionic FeW 11 Z.
