摘要：

This paper studies the adsorption isotherm curves of four amino acids (glycine, aspartic acid, glutamic acid and lysine) and the effects of existences of different concentrations of Cu(II) on them. Both the adsorption isotherm of the amino acids on the kaolinite and that when the copper ion Cu (II) exists belong to the Langmuir type. The slopes of these adsorption isotherm increase with the increasing concentrations of Cu(II) added. It can be explained in terms of formation of the type(I) ternary surface complexes in these systems. The regular pattern of the effects of copper ion Cu(II) on the adsorption isotherm of amino acids on the kaolinite is identical with that of its effects on the exchange and adsorption percentage E (%)-pH on the kaolinite in the same system.
