摘要:
A novel sorptive clay product is formed by treating attapulgite clay with sodium silicate and heating to expel moisture such that the product contains about 7-20% total volatile matter. Acid may also be added such that the pH of aqueous slurry is in the range 5 to 10. This sorptive clay product exhibits water and oil absorption and resistance to wet breakdown equivalent to higher-temperature activated attapulgite products.
