It is shown that an alternative to Kd in describing sorption at low degrees of surface saturation of colloid particles is pH50 which takes into account both the properties of the sorbent and sorbate. The correlations of pH50 with cation charge density for the An(III)-An(IV)-An(V)-An(VI) series and with hydrolysis constants are presented. The redox reactions with plutonium that accompany its sorption onto Fe(III) oxides are discussed.
