| Abstract: | The basic structure of bentonite is described.Two modification methods of bentonite,named activation modification and adding modification methods,are introduced.The main advantages of the two modification methods are analyzed.Besides,the adsorption effect of the dyes in wastewater by modified bentonite are summarized.The results show that modified bentonite has pretty good adsorption effect on the dyes in wastewater.The best removing rate of dyes could reach 99.7%.Furthermore,the adsorption mechanisms,influencing factors and isothermal adsorption equation of modified bentonite are discussed,and the application foreground of modified bentonite in wastewater treatment is looked forward. |
