【Abstract】 Using Na 2CO 3 as modification reagent to improve the CEC (Cation Exchange Capacitence)of Guangfeng bentonite was studied.The effects of the factors such as pulp density,recaction temperature,reaction time and addition quantity of alkali on the Guangfeng bentonite’s CEC were discussed.The bentonite with high CEC of 132.0mmol/100g could obtained at the best experiment conditions.更多还原
