The sorption behavior of phosphorus onto sediment was investigated with the addition of BC derived from incomplete biomass combustion (PC). The sorption kinetic curves of phosphorus onto PC and sediment could be described by a two-compartment first order equation, and the sorption isotherms fit the Freundlich model well. With increasing amounts of PC added, the sorption capacity increased while theHIdid not change much. The distribution of phosphorus forms showed that Casingle bondP (ACa-P plus DAP) constituted the highest fraction in the sediment samples. Throughout the sorption process, Casingle bondP and OP changed very little, but the Ex-P and Fesingle bondP increased obviously, and the presence of PC made this increase more significantly. The high specific area and the presence of iron and aluminum, as well as the modification of the sediments surface properties, make the addition of PC be favorable for the sorption of phosphorus onto sediments.
