- •
Biochar colloid contained numerous oxygen function group and mineral matters.
- •
Cr and Cd adsorption by biochar colloid was greater than that for biochar residue.
- •
RS400 was the most effective Cr(III) and Cd(II) adsorbent.
- •
RS300C was effective for Cr(VI) removal due to its reduction and adsorption.
- •
Dual reaction sites were responsible for effective removal of Cr and Cd by biochar.
