| Abstract: | Hydrotalcite-like materials remove heavy metal from water by four mainly mechanisms: ion exchange,memory effect,chelation and surface adsorption.The application of raw hydrotalcites,calcined hydrotalcites and intercalated hydrotalcite-like materials in heavy metal wastewater treatment and the new progress in its researches were introduced.Various hydrotalcite-like materials,which possessed special properties,could be synthesized by using the mobility of their ionic species and quantities.Therefore the study... |
