【Abstract】 A charge transfer complex of molybdotungstophosphate-3,3′,5′5′-tetramethylbenzidine was studied by UV-Vis and IR spectrometry. The heteropolyanion shows a keggin structure. The maximum absorbance of the charge transfer complex is at 660nm.Its absorbance is linear with the concentration of Mo(VI) in PVA medium.更多还原
