We report the vertical density profiles of Rb(+) and Sr(2+) at the rutile TiO(2)(110)-electrolyte interface for the following bulk electrolyte conditions, [Rb(+)] = 1 mM at pH 11 and [Sr(2+)] = 0.1 mM at pH 10.3, using X-ray reflectivity and resonant anomalous X-ray reflectivity. We find that Rb(+) specifically adsorbs with a coverage of 0.080 +/- 0.003… CONTINUE READING
