Chlorinated organic pollutants constitute a significant category of persistent due to their widespread presence in the environment, which is primarily attributed expansion agricultural and industrial activities. These are characterized by persistence, potent toxicity, capability for long-range dispersion, emphasizing importance eradication mitigate environmental pollution. While conventional methods removing chlorinated encompass advanced oxidation, catalytic bioremediation, utilization biochar has emerged as prominent green efficacious method recent years. Here we review biochar's role remediating typical organics, including polychlorinated biphenyls (PCBs), triclosan (TCS), trichloroethene (TCE), tetrachloroethylene (PCE), organochlorine pesticides (OCPs), chlorobenzenes (CBs). We focus on impact material properties adsorption mechanisms organics. This highlights use sustainable eco-friendly pollutants, especially when combined with biological or chemical strategies. Biochar facilitates electron transfer efficiency between microorganisms, promoting growth dechlorinating bacteria mitigating toxicity organics through adsorption. Furthermore, can activate processes such oxidation nano zero-valent iron, generating free radicals decompose compounds. observe broader application bioprocesses treating soil, reducing impacts. Conversely, water-based integrating proved more effective, leading superior purification results. contributes theoretical practical pollutants.

Abstract The presence of pharmaceuticals in ecosystems is a major health issue, calling for advanced methods to clean wastewater before effluents reach rivers. Here, we review adsorption remove ibuprofen, with focus on ibuprofen occurrence and toxicity, adsorbents, kinetics, isotherms. Adsorbents include carbon- silica-based materials, metal–organic frameworks, clays, polymers, bioadsorbents. Carbon-based adsorbents allow the highest from 10.8 408 mg/g activated carbon 2.5–1033 biochar. Metal–organic frameworks appear promising due their high surface areas tunable properties morphology. 95% published reports reveal that kinetics follow pseudo-second-order model, indicating predominantly governed by chemical adsorption. 70% disclose Langmuir model describes isotherm, suggesting involves monolayer
