Influence of salts on the surface behavior of α-chymotrypsinogen A in aqueous solutions at 298.15 K

•The increase in surface tension is directly proportional to electrolyte mole fraction.•The surface tension of the solvent and the denaturation temperature of the protein are clearly related.•The stabilizing effect of the electrolytes on the protein increases in the order: NaCl
