Spectrophotometric characteristics of dissociation of Zr and Hf complexes with Methylthymol Blue.
Two modifications of the spectrophotometric method for determination of the stability constants of ML and ML(2) complexes are derived and used for determination of the stability constants of Zr and Hf complexes with Methylthymol Blue. The dependence of the degree of dissociation of the complexes on the Zr and Hf concentrations is discussed.
