Synthetic organic dyes, which are resistant to biodegradation, pose a notable health risk, potentially leading cancer and respiratory infections. Researchers have addressed this concern by exploring physicochemical methods remove dyes from wastewater. A particularly promising solution involves modified biochar adsorbents, demonstrate high efficiency in dye removal. Biochar, charcoal-like material derived biomass pyrolysis, offers advantages such as low cost, eco-friendliness, reusability. Beyond its role sustainable soil remediation, proves effective removing wastewater after undergoing physical or chemical modification. Acid–base activation metal–heteroatom impregnation enhances biochar's adsorption capacity. This comprehensive review examines the attributes of biochar, common for production modification, impacts raw materials, pyrolysis temperature, heating rate residence time. It further elucidates mechanism removal assessing factors influencing efficiency, including feedstock, pH, particle size, initial concentration, dosage reaction explores challenges, opportunities, reusability regeneration treating also discusses recent advances using adsorption-based biochar. The ultimately advocates enhancing performance through post-modification.

The Fe3O4–CuS@SiO2 photocatalyst, synthesized via a multistep assembly technique, effectively degraded methyl orange (MO) dye in an aqueous solution under visible light irradiation. solvothermal process generated Fe3O4–CuS nanoflowers, with Fe3O4 nanoparticles initially forming on the CuS surfaces. Subsequently, SiO2 shells were applied to using sol–gel resulting synthesis of photocatalyst. Within 20 min, prepared photocatalyst demonstrated remarkable MO degradation efficiency 94 ± 0.07% and sorption capacity 81.30 mg g−1. This efficacy was attributed synergistic effect between photocatalysis adsorption. superparamagnetic behavior catalyst at room temperature facilitated its high adsorbent recovery rate. proposed mechanism discussed considering various parameters capacity. Langmuir isotherm modeling (R2 = 0.9949) excellent fitting pseudo-second-order kinetics characterized adsorption data. Thermodynamic assessment revealed that is endothermic spontaneous (∆H° 110.0 kJ mol−1, ∆G° −3.03 −14.80 ∆S° 392.27 J mol−1 K−1). Notably, maintained 78% 0.20% after five sorption–desorption cycles for degradation, demonstrating exceptional reusability. These findings underscore superior environmental remediation potential

Dyes abundance in industrial wastewater exerts adverse effects on the environment and human health; adsorption represents a promising remediation strategy. Chitosan-based composites are interesting materials for dye adsorption. In this work, methyl orange (MO) using chitosan (CH) chitosan–graphene oxide (CH-GO) aerogels produced by supercritical gel drying, performed at 200 bar/35 °C, was assessed studying effect of driving force (25–100 ppm) adsorbent dosage (1–8 g/L). It highlighted that difference performance between two adsorbents non-negligible only high concentrations: processing 100 ppm MO solution, qeq is 59 mg/g 28 CH-GO CH, respectively. Starting from 10 8 g/L, it possible to achieve efficiency about 85%, meaning small amounts nanostructured devices can result good process outcomes. Freundlich isotherm reliably describes system behavior (R2 = 0.99). The multi-linear IPD kinetic model confirms case porous devices, there different mass transfer phenomena control molecule diffusion through system. research proposed work aims explore, as first assessment, potential purposes.
