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．

关键词: 液-固界面, 三元表面络合物, E%-pH曲线法

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
