摘要
The solution reaction mechanisms,composition,donor atoms,properties of coordinate link and stability of the complexes on the systems of adrenaline with Na^(3+),Gd^(3+)and Tm^(3+)have been studied by pH-potentiometric titration and electronic spectroscopy.Adrenaline perturbs the f-f electronic transition of Nd^(3+)and Tm^(3+)so that the absorption spectra of their complexes are shifted toward longer wavelengths.The absorption spectra of the complexes formed by the three f-block element ions with adrenaline are shifted toward shorter wavelengths with the increase of PH in Δγ=350～650 nm
