WebThe biochar prepared from different waste biomass resources showed a wide range of adsorption capacity for RB 5 dye. It might be due to the difference in the surface area, pore size and availability of functional groups on the surface of biochar. WebMeanwhile, the capacity of the original biochar (EBC) is only 9.97 mg·g-1. Compared with EBC, CEBC contains more functional groups, such as CO, -OH and -NH 2 . In addition, the pseudo-second-order kinetic model and the Langmuir model are fit to describe the kinetics and isotherms of adsorption of CEBC to Sb 3+ , which suggests that the ...
