| Abstract: | The research actuality of using kaolinite for the disposal of heavy metal wastewater at home and abroad was introduced. The adsorption effects of heavy metals from wastewater on kaolinite are generalized. The influences of pH, adsorption time, initial heavy metals concentration, temperature, modified ways and existing metal irons are analyzed. The adsorption mechanisms, isotherms and thermodynamic of kaolinite are discussed. Furthermore, the development tendency and application prospects of kaolinite in disposal of heavy metal wastewater were forecast. |
