| Abstract: | The structure and property of bentonite were showed. Several modifying methods of bentonite were mtroduced. The adsorption effects of organic pollutants from wastewater by natural bentonite and several kinds of modified bentonite were summarized. The influences of pH, initial concentrations and adsorbent amounts etc. on the adsorption of bentonite were discussed. Moreover, the adsorption mechanisms and rules were dissertated, and applying prospect of bentonite in wastewater treatment were also presented. |
