Adsorption isotherms and kinetics
An adsorption isotherm helps to provide an understanding of
the interactions between the solute and the adsorbent and also
helps in modelling design parameters. The equilibrium data
obtained in this study was analysed using the Langmuir and
Freundlich adsorption isotherm models [30,31].
The linear form of the Langmuir isotherm is expressed in Eq. (2
