  • Peanut shell was selected as the precursors to prepare six biochars under different pyrolytic temperatures (450℃ and 700℃) and times (2,4 and 6 h). Surface properties and elemental compositions of these biochars were analyzed, with an emphasis on their effects on the sorption of diethyl phthalate(DEP) when adding the biochars to soil. The results showed that the surface area and total pore volume of biochar increased as the pyrolytic temperature increased. A longer pyrolytic time also increased surface area and total pore volume, and 4 h was considered an appropriate pyrolytic time. The pyrolytic temperature was the key factor impacting the elemental composition of biochar, while the effect of pyrolytic time was negligible. The increase of pyrolytic temperature strengthened the aromatic properties of biochar and weakened its polarity. Adding biochar to soil significantly enhanced the soil's capacity of adsorbing DEP. The DEP adsorption characteristics of biochar-added soil fitted both the Langmuir model and the Freundlich model. Under all equilibrium concentrations, the contribution of biochar to DEP sorption was between 82.07% and 99.49%, which indicated that biochars played a dominant role in DEP sorption in soil. Correlation analysis found that sorption coefficient (ΔKoc) was significantly correlated to biochar's specific surface area and total pore volume, indicating that increasing biochar's surface area and improving its pore structure could raise the biochar's capacity to adsorb DEP.

Abstract: Peanut shell was selected as the precursors to prepare six biochars under different pyrolytic temperatures (450℃ and 700℃) and times (2,4 and 6 h). Surface properties and elemental compositions of these biochars were analyzed, with an emphasis on their effects on the sorption of diethyl phthalate(DEP) when adding the biochars to soil. The results showed that the surface area and total pore volume of biochar increased as the pyrolytic temperature increased. A longer pyrolytic time also increased surface area and total pore volume, and 4 h was considered an appropriate pyrolytic time. The pyrolytic temperature was the key factor impacting the elemental composition of biochar, while the effect of pyrolytic time was negligible. The increase of pyrolytic temperature strengthened the aromatic properties of biochar and weakened its polarity. Adding biochar to soil significantly enhanced the soil's capacity of adsorbing DEP. The DEP adsorption characteristics of biochar-added soil fitted both the Langmuir model and the Freundlich model. Under all equilibrium concentrations, the contribution of biochar to DEP sorption was between 82.07% and 99.49%, which indicated that biochars played a dominant role in DEP sorption in soil. Correlation analysis found that sorption coefficient (ΔKoc) was significantly correlated to biochar's specific surface area and total pore volume, indicating that increasing biochar's surface area and improving its pore structure could raise the biochar's capacity to adsorb DEP.
