Waste eliminated by waste: Industrial o-phenylenediamine residue derived N,O co-doped hierarchical porous carbon for efficient onitroaniline removal

Puntos clave

• The aim is to develop a method for removing nitroaniline from wastewater using a sustainable carbon material derived from industrial waste.
• Utilized o-phenylenediamine distillation residue to create N,O co-doped hierarchical porous carbon
• Analyzed the porous carbon's effectiveness in removing nitroaniline from water samples
• Conducted tests to evaluate the adsorption capacity and efficiency of the carbon
• The developed porous carbon showed significant adsorption capacity for nitroaniline
• Achieved over 90% removal efficiency in controlled tests
• Demonstrated potential for reducing environmental impact by recycling waste material
