Freundlich Isotherm: An Adsorption Model Complete Framework [PDF]

open access: yesApplied Sciences, 2021
The absolute majority of modern studies dealing with the interpretation of experimental data on the basis of the Freundlich isotherm ignore the fact that the data obtained for regions of low and moderate adsorbate concentration/pressure can be analytically continued within the Freundlich adsorption model to the adsorptive saturation area with coverages

Multiscale estimation of the Freundlich adsorption isotherm [PDF]

open access: yesInternational Journal of Environmental Science & Technology, 2010
Adsorption plays an important role in water and wastewater treatment. The analysis and design of processes that involve adsorption rely on the availability of isotherms that describe these adsorption processes. Adsorption isotherms are usually estimated empirically from measurements of the adsorption process variables. Unfortunately, these measurements

Adsorption Characteristics and Potential of Olive Cake Alkali Residues for Biodiesel Purification

open access: yesEnergies, 2020
Mediterranean countries produce up to 97% of the total global olive production. Besides being a serious environmental burden, olive mill waste represents a potential resource of useful materials for recovery and valorization. In this work, the adsorption
