摘要：
A criterion is proposed for assessing ranges of validity of equilibrium isotherms for phosphate sorption by soils. This criterion is based on the geometrical features commonly exhibited by such isotherms and is analogous to the one that was first formulated by Aharoni and Ungarish in connection with the kinetics of chemisorption reactions. Its use with equilibrium isotherms is illustrated with three widely used expressions for the representation of phosphate sorption by soils but it would also be expected to be useful in connection with sorption of other solutes by soils as well as by other adsorbents.
