Polyoxometalates have attracted great attention because of their high biological activity and low cost features. Three phosphomolybdic heteropolyacid with transition elements V as substituted atom were prepared by aether extraction in the acidic condition. They were charactered by XRD, FT-IR, UV-Vis, ICP and TG-DTA. Analysis results showed the molecular formula of HmPMo12-nVnO40 with Keggin structure. The antibacterial activities of HmPMo12-nVnO40 composites were tested for escherichia coli by the nephelometry method. The results indicated that the complexes showed obvious antibacterial effects on escherichia coli and the inhibition rate reached more than 70%. The activity can be improved more significantly with the increase of concentration of vanadium.
