Solidification/stabilization was an effective method for heavy metal contaminated sediments treatment. The mechanism of solidification/stabilization was mainly about converting heavy metal into more stable fraction through precipitation, adsorption and complexation. The evaluation for solidification/stabilization based on literature reviews about solidification/stabilization technologies widely employed both home and abroad was outlined. Four methods of solidification/stabilization were discussed in light of agents used, namely cement, phosphate, inorganic mixture and organic maters, respectively. The perspective of solidification/stabilization for heavy metal contaminated river sediments were also discussed by summarizing previous research achievements.
