Gl. Starobinets et al., Effect of solvophobic interactions on the molecular sorption of organic substances on a carboxylic ionite from water-nonelectrolyte binary solutions, RUSS J PH C, 75(9), 2001, pp. 1555-1560
The molecular sorption of four aliphatic alpha -amino acids and four antine
oplastic substances on H+-form monocarboxycellulose from six water-nonelect
rolyte (NE) solutions at 293 +/- 1 K were studied. Gibbs free energy of sor
ption-NE mole fraction (N-2) isotherms of sorption from binary solutions we
re measured and examined; the contributions from polar and solvophobic inte
ractions were considered. It was established that, at N-2 greater than or e
qual to 0.3, the solvophobic effect experiences a reversal, which is accomp
anied by a shift of the sorption equilibrium to the binary solution. It was
demonstrated that this phenomenon is closely related to the microstratific
ation of binary solutions.
