β¦ Synopsis
The system vanadium(II1) and the amino acids alanine, aminobutyric acid, glycylglycine and lysine in acid and slightly acid media was studied using spectrophotometric and pH-metric methods. The reactions of hydrolysis reversal and complex formation depending on the concentrations of the components and the pH values were investigated.
