Husk ash of Jatropha curcas seeds were pyrolyzed and charred for 50min at 300~700℃ to obtain biochar after phosphoric acid treatment. The influence of some parameters such as biochar dosage, contact time, and temperature on the naphthalene, anthracene, phenanthrene, and pyrene removal by the biochar was investigated. In addition, the sorption efficiency and mechanism of the biochar on polycyclic aromatic hydrocarbon(PAH) were studied. Results showed that the maximum removal rate of naphthalene, anthracene, pyrene and phenanthrene was 97.4%、94.6%、93.1% and 92.1%, respectively, under the following conditions:temperature 25℃, contact time 60min, the initial concentration of the four PAHs 30mg/L, and dosage of biochar 0.15g. All results suggest that the sorption of the four PAHs by the biochar followed the second-order kinetics model very well. Moreover, the Langmuir model gave an acceptable fit to the experimental data. Maximum uptake of naphthalene, anthracene, pyrene and phenanthrene was 8.849, 8.547, 8.097 and 7.633mg/g, respectively.
