Effect of Tyrosine on the Interaction Between Cu(Ⅱ) and Kaolinite
Abstract:
The interaction among copper ion, tyrosine and kaolinite has been investigated. The effect of tyrosine on the ion exchange percentage of copper ions adsorbed showen by the kaolinite-pH curve, E(%)-pH curve, is found to be characterized by the left-right vacillation. It is suggested that a type Ⅱ ternary surface complex is formed and its stability constant is calculated to be 1 × 101.13.
