Phenol is a priority pollutant that presents significant threat to human health and natural systems when discharged directly into the environment. Consequently, numerous technologies have been used developed eliminate phenol from wastewater streams. These can be categorized physical, chemical, biological methods. While conventional treatment methods are highly efficient in removal; some of these techniques not environmentally friendly others expensive. Therefore, sustainable, green being employed taken consideration due their effectiveness, affordability, environmental compatibility. This review aims highlight physiochemical water demonstrate mechanisms removal technologies. Particular emphasis will given use low-cost adsorbents prepared industrial agricultural wastes for as adsorption processes show highest cost-effectiveness among all

Toxic pollutant contamination of water resources is a significant problem. Numerous aquatic systems are tainted by various hazardous inorganic and organic species introduced wastewater from different human sources, including domestic homes, businesses, farms, mining. Given this, treating the primary environmental challenge. An overview recent advancements in materials based on graphene (Gr) for treatment given this paper. Because its special qualities, Gr, two-dimensional material with remarkable mechanical, electrical, thermal properties, has become capable applications. Here, we have discussed types Gr-based synthesis methods used to materials. The physiochemical properties materials, such as high surface area, mechanical strength, electrical conductivity, chemical stability, optical gas permeability, also been discussed. Finally, application (such removal contaminants, pharmaceuticals, heavy metals, bacteria viruses), existing challenges, future direction concluded remarks. A comparative study terms degradation performance cost compared other provided review. Therefore, comprehensive review emerging paradigm applications, providing insights into their potential impact treatment.

Water depollution via adsorption is an energy-efficient technique that uses activated carbon produced from walnut shells to remove different pollutants. Our research integrates theoretical and experimental approaches comprehensively understand the subject. By analyzing organic functional groups in shell-derived (AC-Ws), evaluating performance, employing DFT analysis, optimizing conditions, we provide valuable insights into application of AC-Ws for removing pesticide pollutants wastewater. The properties this (AC-Ws) are identified by techniques such as XRD, FTIR, SEM/EDX, pHzpc, Boehm titration. A response surface methodology (RSM) has been utilized develop experiment aqueous solutions two herbicides, 2,4,5-trichlorophenoxyacetic acid (2.4.5-T), 2,4-Dichlorophenoxyacetic (2,4-D). Abbreviations technical terms will be explained when first used, objective language used throughout. Grammar spelling conform British standards. examined removal herbicides based on three independent variables; pH, dosage, temperature, within specific ranges (pH: 4–10, dosage: 0.1–0.3 g/L, temperature: 20–40 °C). conducted 17 experiments using Design-Expert software. Optimal conditions included pH 4 dosage 0.3 g/L 2.4.5-T 5 0.1 2,4-D. These demonstrated efficiency 98% desirability function 1.000 92% findings suggest process was thermodynamically favorable exothermic. data described accurately pseudo-second order kinetic model, Freundlich isotherm model showed good alignment with equilibrium data. Using method, functions were adsorbent's surface, density theory (DFT) applied evaluate mechanism sites.
