“…Currently, the research is directed toward treatment processes using less expensive biomaterials, substantially those stemming from plant waste [4]. In recent research studies [5][6][7][8], pomegranate peels have been used as a precursor to prepare activated carbons with a good texture and grand adsorption characteristics. This encouraging result and the availability of pomegranate waste in the southern region of Tunisia have roused us to use activated carbon for water treatment.…”

In this paper, activated carbon-based pomegranate peels was used as a new adsorbent for 2-Nitrophenol adsorption from an aqueous solution instead of the commercial adsorbent Chemviron. Liquid-phase adsorption experiments were conducted, and the maximum adsorptive capacity was determined. The effect of the experimental parameters, namely, initial concentration, solution pH, particle size, temperature, and contact time, were traced. The equilibrium data were mathematically modeled, using the Langmuir, Freundlich, and Temkin adsorption models. The Kinetic data suited the Pseudo-first- order and Pseudo-second-order models at different initial concentration values and particle sizes. The thermodynamic study confirmed that the adsorption process was exothermic and spontaneous and the energy relations substantiated the favorability of adsorption on the prepared activated carbon, leading us to conclude that the adsorption process of the phenolic compound from the activated carbon obtained was physical. Pomegranate peels activated carbon regeneration could be performed using hot distilled water.
