Highly effective adsorption of synthetic phenol effluent by a novel activated carbon prepared from fruit wastes of the Ceiba speciosa forest species

Fruit wastes of the Ceiba speciosa forest species were employed as raw material for preparing activated carbon towards removing phenol from water. Concave cavities spread over entire surface observed characterization results, resulting in a high area, 842 m2 g−1. Adsorption isotherm and kinetic studies performed under best conditions pH (7) adsorbent dosage (0.83 g L−1). An increase temperature 298 K to 328 disfavored adsorption, decreasing 156.7 145 mg g−1 best-fit model, Langmuir. The thermodynamic results indicated that adsorption was spontaneous, favorable, exothermic. concentration decay shows equilibrium is reached at 120 min. pore volume diffusion model (PVSDM) satisfactorily describe behavior. coefficient values range 10−9 cm2 s−1. external internal mass transfer rate-controlling mechanisms. Therefore, application fruit proved very efficient an aqueous medium. alternative suppress water contamination due phenol-derived species.
