Adsorption equilibria of uranium from aqueous solution and seawater on hydrous titanium oxide and amidoxime resin were experimentally determined by batch adsorption experiments. The amount of uranium adsorbed strongly depended on the concentration of carbonium ion. The present work was an attempt to correlate the adsorption equilibrium by taking into account various chemical species of uranium in the solution. The concentration of the chemical species was estimated by mass balance equations and stability constants. The equilibrium could be correlated by the concentration of uranyl monocarbonate ion. An accelerated method for measuring the adsorption isotherm of uranium from seawater was proposed on the basis of the above correlation.
