The interaction of copper-tyrosine -goethite and γ-ALOOH are investigated by the method of E %-pH curve . The E%-pH curves of the ion exchange percentage of tyrosine adsorbed on gocthite or γ-ALOOH are peaked . It is suggested that there is a type I ternary surface complex formation.

Key words: Ternary complex, Liquid/solid interface, E%-pH curve
