| Abstract: | A circulation mass transfer method was used to prepare Na-montmorillonite by exchanging Ca with Na onto Ca-montmorillonite in high concentration sodium chloride solution.The influences of factors on ENa+ were investigated.Alkaline coefficient above 1 of Na-montmorillonite with excellent water swelling property was obtained under these conditions: the minimum concentration of NaCl was 3 %(mass);the concentration of slurry could reach to 25%;time for Na-Ca exchanging was more than 45 min including 15 min stir... |
