Lithium Sorption/Desorption in Some Alkaline Soils: Modeling of the Kinetics Behavior

Abstract Global concern over lithium (Li) in the environment has significantly increased due to its widespread uses. However, literature review on Li kinetics alkaline soils is scant. Hence, batch experiments were conducted quantify and simulate retention release of sandy clay loam soils. Sorption isotherms fitted using Freundlich Langmuir equations. Second-order two site (SOTS) multi-reaction (MRM) models applied sorption/desorption kinetic data. Results revealed nonlinear behavior sorption both studied The maximum capacity ( S max ) for soil (1268.6 mg kg −1 was three-fold higher than (368.9 after 7 days equilibration. exhibited distinctive behavior. MRM SOTS described well by considering reversible irreversible reactions indicate that exhibits a time-dependent restricted desorption kinetic. In contrast, limited sorption, while observed during reaction. Graphical abstract
