<i>Casuarina equisetifolia</i>-Derived Mesoporous Carbon for Adsorptive Removal of Phenolic Pollutants: Insights into Optimization, Isotherm, Kinetics, Thermodynamics, and Mechanism.

ABSTRACT: Herein, Casuarina equisetifolia-derived activated carbon was developed by pyrolysis at a low temperature (773 K). The derived adsorbent was characterized as an extremely porous and amorphous carbon with a surface area of 1007 m²/g. The point of zero charge (pH_PZC) of activated carbon was obtained as 3.89. The reported carbon was used for the remediation of phenolic pollutants [phenol and 2,4-dichlorophenol (2,4-DCP)]. To begin with, the optimization of parameters demonstrated that a pH of 2 and a temperature of 293 K had significant impacts on the adsorption of both pollutants. The isotherm studies revealed that the Freundlich (R ² = 0.9956) and Langmuir (R ² = 0.9866) models better fitted the adsorption of phenol and 2,4-DCP
