This study explores the conversion of cooked rice waste (CRW) into an affordable, activated carbon material with effective adsorption capabilities. Activated carbon (AC) was initially produced through combustion under a nitrogen atmosphere at 550 . The resulting charcoal was then chemically activated using phosphoric...
Heavy metal pollution has posed a significant threat to environmental and human health. In this work, activated carbon synthesized from shrimp shells through KOH activation was employed as an adsorbent for Fe³⁺ ion removal from aqueous solutions. The material was characterized using X-ray diffraction, scanning electron...
This investigation focuses on the abatement of methyl violet (MV) dye from industrial effluents using the deployment of functionalized biochar prepared from methanol‐extracted groundnut shell residue. The biochar was functionalized by 30% tartaric acid(C4H4O6) to boost the surface functionality and adsorption performan...
The widespread occurrence of pharmaceutical contaminants, especially ciprofloxacin (CIP), in aquatic environments has created an urgent need for efficient and environmentally friendly water treatment strategies. In the present study, a green manganese oxide palm leaf biochar (MnO2/PL biochar) nanocomposite was synthesi...
Agricultural by-products such as peanut shells provide a renewable alternative to coal-based activated carbon by combining wastewater-treatment potential with agricultural waste valorization. This review examines the performance of peanut shell-based activated carbon (PSAC) in dye adsorption and evaluates the kinetic,...
