抄録

Adsorption phenomena of Sn (II) and Pd (II) ions on α-alumina were quantitatively analysed using α-alumina powder. Sn (II) ions adsorbed on α-alumina surface obeying a Fowler-Frumkin type adsorption isotherm, and Pd (II) ions adsorbed on Sn (II) pre-adsorbed α-alumina obeying a Langmuir type isothem. In both cases, Cl- ions played major roles by offering adsorption sites for Sn (II) ions and by controlling stable ionic species of Sn (II) and Pd (II) in the solutions by coordination. The surface states of α-alumina and the ionic species were also affected by the pH of the solutions, resulting in considerable influence on the adsorption phenomena.
