Abstract: The D NMR spectra of Mg, Ca and Hg-BDTA(meso-2,3-Butanediaminetetraacetate) complexes were investigated in this paper. The thermodynamic parameters are obtained by the complete line shape analysis and the △S values are explained by the H2O displacement mechanism. It is discussed that the chemistry shift differences of Zn, Cd, Pb, In, Sc, La and Lu-BDTA depend on the temperature.
