| Abstract: |
| The highly pure chelates of Glycine-Cu, Glycine-Zn and Lysine-Zn were prepared by organic solvent, and the synthetic conditions were investigated according to the molar ratio of ligand, pH and reaction time and temperature. In the mean time, the products were analyzed by chemical method, atomic absorption spectroscopy and IR spectrometry. |
