Abstract

The mobility of metal ions in the environment may be affected by their interactions with oxides of aluminium. The retention on alumina (Al2O3) of divalent metal ions is examined as a function of pH. The pH50 (the pH required for 50% retention) is inversely proportional to pK1 (first hydrolysis constant of metais) and defines the selectivity sequence of the substrate for the divalent cations: Pb > Zn > CO > Cd.
