Abstract
Data on the solubility of argon in water and aqueous solutions of L and D enantiomers of α-valine and α-phenylalanine at T = 283-328 K and partial pressure of argon p2 = 0.1 MPa are used to calculate the standard parameters of the Sechenov salt effect. Parameters of the solute–solute pair interaction are estimated within the formalism of the McMillan–Mayer theory. Evidence is provided for the presence of the chiral effect in the Sechenov parameters.
