摘要:
Remediation of heavy metal–contaminated soil and water bodies necessitates the continuous development of effective decontamination techniques. To address this issue, ferromanganese binary oxide–biochar composites (FMBC) were prepared using impregnation/sintering methods, and their physicochemical properties and morphologies were examined. Kinetic modeling and adsorption isotherms were used to characterize the adsorption of Cu(II) and Cd(II) on FMBC, revealing that adsorption was well represented by pseudo-second-order kinetics (R2>0.99) and the Langmuir isotherm model. The prepa...
