| Abstract: | Bentonite has highly adsorptive capacity and through the modification of it, the removal capacity of heavy metal ions can be improved. The modified bentonite applied to the treatment of the wastewater containing heavy metal ions by the scholars both in China and abroad has been studied. The preparation and characterization methods of bentonite are reviewed. The main factors affecting the adsorption of heavy metals are discussed. The research progress on the adsorption of heavy metals, such as Cr6+, Cd2+, Hg... |
