Spectrophotometric determination of equilibrium constants of two mutual competitive reactions by the method of isosbestic points.
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.
