[0048] Preparation of Purified Sodium Bentonite
[0049]The preparation process of purified sodium-based bentonite is as follows: Naturally dry and crush the raw sodium-based bentonite, then dry it by airflow, and then grind it by Raymond mill, and then obtain purified sodium-based bentonite by wind selection and classification by airflow classifier, performance index for E Na+ / CEC×100%≥50%.
[0050] Preparation Example
[0051] Step a: Weigh 15 g of aluminum metaphosphate, 30 g of NaOH, 10 g of sodium molybdate, and 30 g of deionized water, and add them into a reactor at 90° C. to stir and keep the temperature constant for 10 min.
[0052] Step b: Put 300g of deionized water in the above-mentioned reactor and mechanically stir at 100-300rpm at room temperature.
[0053] Step c: Weigh 1161g of deionized water and put it in another larger reactor at room temperature, add 4g of surfactant H140 and stir slowly at 30-50rpm, add the catalyst prepared in the above step b until m...
