Hysteresis in the individual and competitive sorption of cadmium, copper, and…

Abstract. Investigations of the sorption of heavy metals by soils often involve a fast ion-exchange process followed by a more sorbate-specific slow process. Desorption and sorption isotherms often fail to coincide, thus showing real or artifactual hysteresis, and failure to conform to conventional models generally prevents meaningful comparison of the hysteretic behavior of different sorba…
