Abstract

The adsorption of adenine nucleotides with different phosphate chains from aqueous solutions onto nanocrystalline ceria surface was investigated. The adsorption dependences of pH and ionic strength are interpreted in terms of surface complexation theory.  The equilibrium reaction constants of  the formation of outer-sphere electrostatic complexes are calculated with using basic Stern model for double electric layer.
