Isotherm and Kinetics of Phenol Removal by Adsorption- A Review

Phenol is one of the major pollutant in wastewater. Various methods are available for phenol removal, both biological and non biological. Phenol removal by adsorption is widely studied area of investigation. The kinetics and isotherm studies are major part of studies carried out in this regard. These studies are important with respect to adsorption capacity, loading and time. The current review aims at presenting the summery of the research carried out in order to investigate isotherm and kinetics. It was observed during this review that in most of the investigations solute uptake kinetics was second order in nature and Langmuir isotherm was better fitted to the data.
