Investigation of Langmuir and Freundlich Adsorption Isotherm of Pb2+ Ions by Micro Powder of Cedar Leaf

ABSTRACTIn this work, the micro powder was the product of cedar leaf (MPCL) is used as a low-cost adsorbent for the removal of Pb2+ ions from aqueous solutions. Bath experiments were used to determine the best adsorption conditions The adsorption percentage of Pb2+ ions MPCL samples at different initial pH, contact time (tc), adsorbent dosage and temperature (T) were investigated. Effective rem...

Multiscale estimation of the Freundlich adsorption isotherm

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 are usually contaminated with errors that ...

A modified Langmuir-Freundlich isotherm model for simulating pH-dependent adsorption effects.

Analytical isotherm equations such as Langmuir and Freundlich isotherms are widely used for modeling adsorption data. However, these isotherms are primarily useful for simulating data collected at a fixed pH value and cannot be easily adapted to simulate pH-dependent adsorption effects. Therefore, most adsorption studies currently use numerical surface-complexation models (SCMs), which are more...
