Humic acid was coordinated with metal oxide or sulfomethlated to prepare modified humic acid as eluent. Metal copper ion and polycyclic aromatic hydrocarbon phenanthrene were selected as objects to study leaching characteristics of modified humic acid on Cu2+ and phenanthrene. The results showed that the leaching effect of humic acid metal complex and humic acid sulfonate on phenanthrene was superior to humic acid, while the humic acid metal complex produced poorer effect than the other two. Metal copper ion interacts with phenanthrene under the influence of each other in the soil leaching experiment. The leaching rates of three kinds of eluent on Cu 2+ were increased with the increasing of pH range 3-7, after the pH was higher than 7, the leaching rate decreased, but the change of leaching rates of modified humic acid on phenanthrene were not obvious under different pH conditions. © 2011 IEEE.
