摘要：

The Polanyi potential Delta F = -RTln(p/p(s)) was demonstrated to adequately describe the sorption equilibrium between water vapor and a CaCl2-in-silica gel composite sorbent. Approximation formulas for calculating the dependence of the value of adsorption of water on Delta F and the dependence of heat of sorption on the adsorption value were derived. A comparison of experimental and theoretical data for a temperature-independent curve and sorption isobars was performed.
