Formation of binary complexes of Al(III), Cr(III), Fe(III), Th(IV), UO2(II), Ce(III), La(III), and Gd(III) with 3-(2-ethylamino)-1-hydroxyethyl] phenol (Effortil) were studied potentiometrically at 37.0 °C and I = 0.16 mol dm−3 NaNO3 in aqueous solution. The acid–base properties of Effortil were investigated and discussed. The order of stability of the complexes was investigated and is discussed in terms of the metal ion. The experimental pH titration data were analyzed in order to evaluate the formation constants of various intermediate species formed. The concentration distribution of various species formed in solution was evaluated.
