We have developed a method that makes use of dual isosbestic points in a dual ligand, single metal system that allows the determination of the equilibrium constants of complexes in which two ligands compete for the same metal ion, and one complex is colourless. The competition of methyl thymol blue and citrate was used to test the model.
Ternary Al70Cu20Fe10 alloy nano-composites prepared by mechanical alloying are characterized by X-ray diffraction (XRD) and X-ray absorption fine structure (XAFS). The results indicate that after milled for 10 hours, the coordination environment around Cu atoms is changed largely and becomes disordered, but the local structure of Fe atoms still remains as… (More)
This paper reports a new method for determining the stability constants of ternary complexes, based on analysis of isosbestic points. First, it is necessary to determine the absolute molar absorptivities of the various species concerned, then their concentrations and the stability constant. In this method, the approximate treatment of classical photometric… (More)
