Abstract：In this paper, ZnSO4-impregnated biochar (PRZn) was subjected to high temperature (60℃ and 90℃) abiotic aging for six months. The characteristics of biochar properties after aging were determined by elemental analyzer, specific surface area analyzer, X-ray photoelectron spectroscopy and Fourier transform infrared spectroscopy. The effect of aging on the adsorption performance of Pb2+ was comparatively studied with aged biochars and pristine biochars. The results indicated the free radicals (methyl radicals) generated by high temperature aging process led to the increasing of oxygen-containing functional groups content on the surface of biochars. The specific surface area of biochars pyrolyzed under 500℃ was greatly increased after aging (from 24.67m2/g to 85.51m2/g), while Zn oxides introduced from modification process were transformed from crystal structures to organic bound forms. The adsorption capacity of Pb2+ was increased from 31.18mg/g to 47.70mg/gbecause of aging processes. However, a slight decrease of oxygen functional groups and Pb2+ adsorption capacity (36.05mg/gdecreased to 31.92mg/g) was observed for biochars pyrolyzed under 700℃ after ageing at high temperature (90℃), mainly because a self-quenching effect of reactive substances at high ageing temperature and a stable structure for biochar pyrolyzed at 700℃. Findings of this study can provide new insights to the long-term utilization of modified biochar in lead-contaminated soil.
