Determination of the proportion of free and bound sorbate in systems with permanent sorption-desorption hysteresis

A unique method of calculating the quantity of free and bound solvent on different sections of sorption isotherms, which is applicable to any systems with permanent hysteresis is proposed. The calculation is applied to the nitrocellulose-ethyl acetate system, the sorption behaviour of which differs...

Description
Summary:A unique method of calculating the quantity of free and bound solvent on different sections of sorption isotherms, which is applicable to any systems with permanent hysteresis is proposed. The calculation is applied to the nitrocellulose-ethyl acetate system, the sorption behaviour of which differs in a number of respects previously unknown.
