摘要：

Herein, we have described the important role about biochar aging on the basis of sorption performance of phenanthrene. Biochar used in this study was produced from rice husks at 350 degrees C and its aging has been manufactured by laboratory incubation. The results showed that an aging layer formed which contains oxygen-bearing groups on to the surface increased during the course of aging. Aging decreased the adsorption capability of biochar obtained under low temperature by 34.10%, ascribed as the increase of oxygen bearing polar moieties; specifically the hydroxyl species that negatively affected sorption of phenanthrene.
