Adsorpdon behaviors ofNi(II), Co(II), Sr(II), and(I) ions were nvestigated on amorphous alumina with varying pH at three different etalion concentrations under the condition of 0.I M ionlc strength.With increasingmctalion concentration, the percentage of adsorption decreased and the adsorption edge was shifted to a higher pH value. The adsorption data obtained usingthe metal ion concentration of $1.0{\times}10^{-4}$M were quantitatively analyzed by surfacecomplexation modelingof Ni(II) and Co(II) ions adsorbed at high pH (>8)were found to be in hydrolyzed forms.
