Natural Calcium bentonite was sodium retrofitted with ultrasonic treatmeant,using the sodium cation exchange resin as sodium retrofitting agent.The effect of the condition on the yield of sodium montmorillonite was studied in the experiment.The optimium condition for the preparation of sodium montmorillonite was determined,that is：the concentration of slurry is 9 %,the mass ratio of the resin to natural Calcium bentonite is 0.5∶ 1,the ultrasonic reaction time is 40 minutes,the temperature is 70 ℃,and the yield is 49.55 % under these condition.The cation exchange capacity（CEC） of the sodium montmorillonite prepared was 97.19 mmol/100 g.The XRD analysis indicated that its d001 layer spacing was 1.285 9 nm.
