New data on Sepiolite and Attapulgite - Volume 5. Hydrothermal studies have failed to yield synthetic attapulgite or sepiolites in the system MgO-Al 2 O 3-SiO 2-H 2 O. However, the natural minerals can be decomposed to yield mont-morillonoids by mild hydrothermal treatment as low as 200°C and probably as low as 100°C.

straw-like structure also gives attapulgite and sepiolite stronger capillary action. It could be assumed that higher capillary attraction would make attapulgite and sepiolite more effective at removing impurities, but the situation is actually the opposite. In addition to impurities, attapulgite and sepiolite absorb large The complete guide ...

INTRODUCTION. The silicate minerals such as zeolite, attapulgite, kaolinite, smectite, and sepiolite are found to be effective as non-toxic, cheap, ecologically advantageous and affordable materials based on their high sorption capacity and ion-exchange properties (Murray, 2000; Slamova et al., 2011).So they are widely used in many fields of industry, agriculture, …

The investigated sorbents were bentonite, calcium bentonite, zeolite, calcium lignosulphonate, activated charcoal, sepiolite, attapulgite and ground attapulgite, and silica. Samples of these were supplied by Certech (Niedomice, Poland). The feed used for the tests was prepared from naturally contaminated grain.
