Abstract

Adsorption of chlorpyrifos (CP) by giant reed(Arundo donax L.)derived biochars obtained at 300-600°C and their corresponding de-ashed biochars was investigated.With increasing pyrolysis temperature,the adsorption capacity(Qe) of CP ontothe biochars increased. The maximumvalues of Qe of CP by the water-washed biochars (WBCs) and de-ashed biochars (BCFs)produced at 600°Cwere 4.8mg/g and 8.9 mg/g, respectively.Pore-filling, - electron donor-acceptor interactionand hydrophobic interaction were the underlyingmechanismsresponsible forCP adsorptiononto these biochars.
