摘要
The constants of copper (II) complexation with alpha-L-alanine in water and water-formamide solvents were determined potentiometrically at 298 K; the dissociation constants for alanine amino group was also determined. It was found that the stability of the [CuAla]( ) complex is significantly reduced with an increase in the formamide content in solution. The heat balance of the Cu(2 )-alanine-water-formamide system was considered for the process of Cu(NO(3))(2) transfer from water to an aqueous solution of alanine using the earlier determined K (stab) and thermochemical data.
