Abstract—The heats of complex formation in the L-phenylalanine–copper(II) ion system in aqueous solution
were determined calorimetrically at 288.15, 298.15, and 308.15 K for an ionic strength of 0.5 (KNO3 supporting
electrolyte). The thermodynamic parameters of formation of phenylalaninatocopper(II) complexes were calcu-
lated for various temperatures.
