Mathematical Modeling of Groundwater Flow and Solute Transport in Saturated Fractured Rock Using a Dual-Porosity Approach (2014, background): “Malik (2004) introduced a dimensionless equilibrium parameter called a separation factor, which simply delineates the adsorption to be irreversible when RL 1⁄4 0; favorable when RL falls between 0 and 1; linearly favorable when RL 1⁄4 1; and unfavorable when RL is greater than unity.”
Adsorption of dyes using different types of clay: a review (2017, background): “However, due to it being a limited natural resource, slow adsorption kinetics and low adsorption capacity of bulky adsorbate because of its microporous nature, disposal problems and also the high cost and difficulty of regeneration, a search for cheap, effective adsorbents such as clay derivatives h”
