3. Theory of adsorption isotherm and kinetics
3.1. Isotherm models
Adsorption isotherm is basically important to describe how
solutes interact with adsorbents, and is critical in optimizing the
use of adsorbents. The Langmuir [19], the Freundlich [20] and the
Temkin [21] were employed in the present study. The linearized
forms of the three isotherms are
