Orange peel magnetic activated carbon for removal of acid orange 7 dye from water.

ABSTRACT: Magnetic activated carbon resources with a remarkably high specific surface area have been successfully synthesized using orange peels as the precursor and ZnCl₂ as the activating agent. The impregnation ratio was set at 0.5, while the pyrolysis temperature spanned from 700 to 900 °C. This comprehensive study delved into the influence of activation temperatures on the resultant pore morphology and specific surface area. Optimal conditions were discerned, leading to a magnetic activated carbon material exhibiting an impressive specific surface area at 700 °C. The Brunauer-Emmett-Teller surface area reached 155.09 m²/g, accompanied by a total pore volume of 0.1768 cm³/g, and a mean pore diameter of 4.5604 nm. The material displayed noteworthy properties, with
