Novel Zn-Fe engineered kiwi branch biochar for the removal of Pb(II) from aqueous solution

Yuehui Tan et al.

Summary: The study compared the adsorption efficiency of a novel adsorbent KB/Zn-Fe made from kiwi branch biochar modified with Zn-Fe with original biochar for Pb(II) removal from wastewater. Results showed that KB/Zn-Fe had a higher maximum adsorption capacity for Pb(II) in aqueous solution compared to original biochar, and the adsorption capacity decreased with increasing biochar dose. Co-existence of NO3- had little impact on the absorptive capacity of KB/Zn-Fe, while Cl- enhanced the adsorption capacity. Multiple adsorption mechanisms by KB/Zn-Fe were identified, providing guidance for future production of biochar with efficient adsorption ability.
