@@@@Highlights •Biochar was modified by combined nanoparticles loading and functional groups grafting.•BC-Fe-S had excellent Pb(II)/Cd(II) uptake performance with fast adsorption kinetics.•Sulfuration and Fe2O3 modification were believed to enhance heavy metals uptake.•Chelation, ion exchange and co-precipitation were mainly involved in uptake process.•Pb(II)/Cd(II) were efficiently eluted by HCl and BC-Fe-S was effectively recycled.
