Latrous, J. Oliver] Self-diffusion coefficients D of the trivalent aquo ion Cm3+ have been determined in aqueous Nd(ClO4)3−HClO4 solutions (pH 2.5) at 25°C, by the open-end capillary method (O. E. C. M.). The variation of D versus the square root of the concentration of inactive solution is an exponential form in the studied range of concentration. The limiting value D0 at zero ionic strength is 6.0·10−6 cm2·s−1. The curve $$D = f(\sqrt c )$$ relating to Cm3+ can be compared to those of241Am3+ and153Gd3+ obtained under similar conditions. We find a similar ionic structure of Cm3+ with Am3+ and Gd3+. They have the same hydration as a tripositive of 5f and 4f ions in the absence of hydrolysis, complexing, or pairing at pH 2.5. The present study contributes to show the analogy of the solvation structure of trivalent actinide ions in aqueous solution at pH 2.5 with that of the trivalent lanthanide ions as a help for predicting the thermodynamic properties.
