Removal of polycyclic aromatic hydrocarbons from aqueous solution using plant residue materials as a biosorbent

► Polycyclic aromatic hydrocarbons are effectively removed by plant residues. ► Biosorption mechanism of plant residues to abate PAHs is a partitioning process. ► Partition coefficients are negatively related with sugar contents of biosorbent. ► The aromatic component and Kow exhibit positive effects on biosorption. ► The structure-effect relationship guides plant residue using as a biosorbent.
