Abstract

A further approach to derive the thermodynamic sorption equation for aqueous phase was performed by estimating the molar heat of sorption (ΔHs) accurately. On the basis of the findings that the sorption of a volatile compound depends on both its molar heat of mixing into film and its enthalpy change toward film, the following equation could be successfully derived: S = S0 exp γ, [Vv[(δwv)2 —, δc2]/RT]. The plots of In S into LDPE film vs the term of the equation gave more adequate improvement in the correlation (r = 0.968). Taking into account the volatility (α) of a volatile compound from solution, further improvement of the equation was made: S = α, S0 exp γ, [Vv[(δwv)2 —, δc2]/RT]. The plots of In S/α, vs the term of the equation for both sugar-ester and SDS solutions gave a sufficient correlation (r = 0.959). Furthermore, the equation could be sufficiently applied to various polymers (PP, r = 0.931, EVA, r = 0.963, EVOH, r = 0.932).
