Adsorption of brilliant cresyl blue using NaOH-activated biochar derived from sewage sludge

E3S Web of Conferences, Год журнала: 2025, Номер 601, С. 00087 - 00087

The treatment of sewage wastewater generates a substantial amount sludge, which poses significant ecotoxicological and environmental challenges. Managing this sludge is critical, as traditional disposal methods carry risks: agricultural use can lead to contamination, while landfill raises concerns about solid waste management the preservation sites. Our research focuses on converting urban into activated carbon. We employed various techniques characterize NaOH-activated biochar, including infrared (IR) analysis. BET analysis revealed specific surface area 62.35 m 2 /g. also assessed biochar for its effectiveness in adsorbing brilliant cresyl bleu (BCB). SSE error calculations indicated first-order adsorption, isotherms suggested better fit with Sips model, indicating heterogeneous adsorption an ns value 0.95. study highlights dyes such BCB.
