Abstract
Abstract Adsorption of 11 metal acetylacetonate complexes onto an octadecylsilica(ODS) gel from an aqueous solution was measured as a function of pH. It was found that the pH dependencies regarding adsorption are almost consistent with those of a solvent-extraction system, except for Zn(II) which is unextracted into benzene. Plots of the adsorption ratio against pH indicates the 1:1 complexes are adsorbed onto ODS gel, except for Al(III) whose composition is 1:2.
