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.

生和改性石榴皮在废水处理中的应用：文献综述与分析

在废水处理中，使用可再生基质作为生物吸附剂备受关注。石榴皮（PGP）构成这些底物之一。进行了审查，以研究石榴皮（PGP）在废水处理中的潜力。介绍了物理和化学PGP特性，并将其与突尼斯石榴皮（El Gabsi）的特性进行了比较。评估了原始和改良的PGP性能以及对金属，染料和有机污染物的吸附能力。说明了文献中使用的不同实验吸附条件，例如浓度，接触时间，pH，温度和吸附剂剂量。研究和最适合的动力学和等温线模型与实验数据和热力学参数进行了比较。提出了激活物理和/或化学条件对激活的PGP性能的影响。与该活化形式相比，本文揭示了用于废水处理的原始PGP的显着特性。活化和原始PGP形态之间的比较表明，活化并不一定会提高PGP的吸附能力。尽管对原始PGP生物吸附剂进行了有限的研究，但从这项研究中可以看出，它具有非常好的吸附性能，与其他各种农业废生物质相比，它是一种严肃且低成本的可再生基质，可用于废水处理的实际应用。活化和原始PGP形态之间的比较表明，活化并不一定会提高PGP的吸附能力。尽管对原始PGP生物吸附剂进行了有限的研究，但从这项研究中可以看出，它具有非常好的吸附性能，与其他各种农业废生物质相比，它是一种严肃且低成本的可再生基质，可用于废水处理的实际应用。活化和原始PGP形态之间的比较表明，活化并不一定会提高PGP的吸附能力。尽管对原始PGP生物吸附剂进行了有限的研究，但从这项研究中可以看出，它具有非常好的吸附性能，与其他各种农业废生物质相比，它是一种严肃且低成本的可再生基质，可用于废水处理的实际应用。
