Spectrophotometric and polarographic study of Uranium in acetate medium in the presence of resorcinol

The redution of uranyl ion is studied in acetate buffer containing resorcinol. Two waves were obtained for all pH. Resorcinol can be used as a maximum suppressor. Complexation of uranium with resorcinol is accompanied by a decrease in diffusion current and shift of half-wave potential to more negative values. Mixed complexes of acetate and resorcinol are formed with uranium. Resorcinol is found to stabilize the pentavalent uranium by complexation
