摘要:

采用E%-pH曲线法研究铜-酪氨酸-针铁矿、γ-AlOOH两个体系三者间的相互作用,发现其E%-pH曲线为单向上升的峰型曲线,认为在上述两体系中均有I型三元表面络合物生成.

Abstract:

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
