中文摘要	the electrochemical transfer behaviour of vanadium-containing heteropolytungstate anions [pw12-xvxo40]((3+r)-) (x = 1-4) across the water \nitrobenzene interface has been investigated by cyclic voltammetry and chronopotentiometry with cyclic linear current scanning. the transfer of pw11v1o404-, hpw10v2o404-, h2pw10v2o403-, h3pw9v3o403- and h4pw8v4o(40)(3-) across the water \nitrobenzene interface can be observed within the potential window. the effects were observed of ph in the water phase on the transfer behaviour and the formation of vanadium-containing heteropolytungstate anions in solution. heteropolytungstate anions become more stable due to their involving the vanadium atom. the degree of protonation and the dissociation constant of the trivalent vanadium-containing heteropolytungstate anion of protonation increase with increasing vanadium content. the transfer processes are diffusion-controlled the standard transfer potential, the standard gibbs energy and the dissociation constant for vanadium-containing heteropolytungstate anions have been obtained and the transfer mechanisms are discussed.
