Yellow 12-molybdenum phosphoric acid-dextran solution was prepared by stirring 1g 12-molybdenum phosphoric acid powder in a 10% dextran solution at 25℃and pH=2.The solid solution was obtained by casting the yellow solutioin on glass plate and drying thereon in dark place. The spectral properties of the yellow inclusion solution and solid solution were studied by DSC,ESR,XPS,IR,UV Vis and XRD. It was concluded that the inclusion compound of 12 molybdenum phosphoric acid with dextran was formed in form of both solution and solid solution.

Key words: 12-Molybdenum phosphoric acid, Dextran, Inclusion compound, Supermolecule
