Abstract: |
The research development on the removal of heavy metal ions from aqueous solution by flocculation was reviewed, including the inorganic flocculants, organic macromolecule flocculants, microbiological flocculants and complex flocculants. The category of flocculants, mechanism of flocculation and application in removal of heavy metal ions from aqueous solution were introduced in detail. The flocculants holding high removal efficiency, safety, harmlessness and without secondary pollution, especially, the microbiological flocculants would be promising for the treatment process of micropollution water based on heavy metals.
