“…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.

“…e results indicated that the second-order model provided the best fit to adsorption kinetic data, and the intraparticle diffusion model had an insignificant role at the initial stage of the adsorption process. Adsorption capacity of modified PGP for phenol removal was evaluated by Zarroug et al [42]. e biosorbent was prepared as described in Section 3.1. e maximum adsorption capacities for three (time and temperature) activation conditions used, (2 h, 300 K), (3.5 h, 350 K), and (3 h, 400 K), were found to be 109 mg/g, 96 mg/g, and 103 mg/g, respectively.…”

The use of renewable substrates as biosorbents has a great attention in wastewater treatment. The pomegranate peel (PGP) constitutes one of these substrates. A review is carried out to investigate the potential of pomegranate peel (PGP) for wastewater treatment. Physical and chemical PGP properties are presented and compared to those of Tunisian pomegranate peel (El Gabsi). Raw and modified PGP performance and sorption capacity for metals, dyes, and organic pollutants are evaluated. Different experimental sorption conditions such as concentration, contact time, pH, temperature, and adsorbent dose used in the literature are illustrated. Studied and best-fitted kinetics and isotherm models to experimental data and thermodynamic parameters are compared. The effects of activating physical and/or chemical conditions on the activated PGP properties are presented. This paper reveals noteworthiness properties of raw PGP for wastewater treatment compared to this activated form. The comparison between activated and raw PGP morphology exhibits that the activation does not necessarily improve the PGP adsorption capacity. Despite a limited research carried out on the raw PGP biosorbent, it appears from this study that it has very good adsorption properties, making it a serious and low-cost renewable substrate toward practical applications in wastewater treatment compared to various other waste agricultural biomass.
