摘要: The stability constant on complexation of VO 2 + with glutamic acid (Glu) in mixed solvent systems methanol water and free-energy changes have been determined spectro-photometrically a temperature variation method 0.2 mol dm -3 sodium perchlorate as ionic medium the pH range (1.3-5), high ligand-to-metal ratios. Linear relationships are observed when log K is plotted versus 1/D, where D represent dielectric system, respectively. results discussed terms effect protonation complexation.
