Effective removal of methylated phenol and chlorinated phenol from aqueous solutions using a new activated carbon derived from Halodule uninervis waste
Source abstract
Abstract
Abstract Due to the toxicity of methylated and chlorinated phenols, it is necessary to remove them from aqueous solutions. Therefore, a highly efficient adsorbent was developed from the dead leaves of Halodule uninervis seagrass (SG) through a chemical and thermal activation process. The prepared activated carbon (SGAC) was characterized and investigated for removal of 2,4-Dimethylphenol (DMP) and 2,4-Dichlorophenol (DCP) from aqueous solutions. The batch adsorption mode was used and the effects of adsorption conditions were studied. SGAC adsorbent showed high adsorption capacities which were 364 mg DMP/g and 333 mg DCP/g. The adsorption experimental results fitted Freundlich and Langmuir models and followed pseudo-second-order kinetics. The adsorption of both adsorbates was spontaneous. The prepared adsorbent was able to remove 90% of DMP and 97% of DCP from the synthetic wastewater. This study indicated that SGAC adsorbent is efficient and reusable in the synthetic wastewater for at least four times.
