Biochar (Dec 2022)
Pb(II) adsorption by biochar from co-pyrolysis of corn stalks and alkali-fused fly ash
Abstract
Highlights A new type of biochar was prepared by co-pyrolysis of corn stalks and alkali-fused fly ash for Pb(II) removal from wastewater. The high surface area and Pb(II) adsorption capacity of adsorbents made them suitable for wastewater treatment. The main Pb(II) adsorption mechanisms were physisorption, precipitation, cation exchange, and complexation.
