Development of the Synthesis of Chromium and Molybdenum – Amino Acid Complexes: A Green Chemistry Approach
Some concepts of green chemistry were applied on the Synthesis of Chromium(III) and Mo(V) complexes with amino acids. Three concepts were used in this research were changing to safer solvent, using less energy and appliying a shorter process. The optimum pH of the complex formation of Chromium (III) is 4, whereas for Mo(V) complex, the most stable condition is at pH=1. The products were characterized by physical properties, Infrared and Uv-Vis spectrophotometer, Atomic Absorbtion Spectrophotometer, Elemental Analysis, and VSM (Vibrational Sample Magnetometer). The molecular formula of the complexes were predicted by simulation from the composition and the magnetic properties.
