摘要

Abstract

Converting peanut shells into biochar by pyrolysis was considered an environmentally friendly and efficient method for agricultural solid waste disposal. The properties of peanut shell-derived biochar (PBC) under different temperature and its adsorption capacity of heavy metals were investigated. It was found that PBC400 exhibited the highest cumulative capability for heavy metals elimination in single solute because of its high specific surface area and rich functional groups. Furthermore

the competitive adsorption revealed that PBC had a substantial difference in adsorption affinity from diverse heavy metal ions

sorption capacity decreased as Pb

which was lower than in a single solute. The adsorption process using selected biochar was optimized with respect to pH

reaction time

adsorbent dose

and initial concentration of heavy metals. The kinetic data was well fitted with PSO model

and the Langmuir model was adopted for adsorption equilibrium data in both cases of single solutes and mixed solutes for all heavy metals

which indicated that the removal

course was primarily explained by monolayer adsorption

and chemical adsorption occupied an important role. Therefore

peanut shells derived biochar could be a potential and green adsorbent for wastewater treatment.
