Abstract

The increasing attention in academic and industry research on per and Poly-Fluoroalkyl compounds (PFAS) in the environment is a result of growing concern. If PFAS are exposed to human health, they are also known to be dangerous. Utilizing leftover lignocellulosic biomass, biochar is a pyrolytic material that can be used as an inexpensive adsorbent to remove environmental pollutants. It is essential to adjust the physical and chemical properties of biochar due to its low concentration and distinct chemical composition. Most notably, char's high surface area and C and N content are the primary controlling elements during PFAS adsorption. This summary provides background information on PFAS pollutants and possible remediation strategies.
