Speciation of the new ligand di-isopropyliminodiacetoamide with Cu(II) using computational processing and graphical methods
摘要:
The importance assigned to chelating agents in diverse areas has impelled studies concerning their development as related to metal ions representing a biological concern. The synthesis of di-isopropyliminodiacetoamide (D) is presented in this work. The acidity constant obtained for D was pK(a) = 5.79 +/- 0.04 with the aid of program SUPERQUAD. The equilibrium constants for D with Cu(II) were obtained with the aid of program SQUAD for CuD2+ and CuD22+ species giving log beta(1) = 4.795 +/- 0.002 and log beta(2) = 8.374 +/- 0.004, respectively.
