Doxazosin adsorption in natural, expanded, and organophilized vermiculite-rich clays

Cerâmica, 2022
Vermiculite clays are adsorbent materials that have good chemical adsorption capacity, which makes them applicable in the removal of drugs from aqueous solutions. Their lamellar structure can be easily expanded and organophilized.

Justification of the opportunities of obtaining silicate materials based on clay waste adsorbents [PDF]

E3S Web of Conferences, 2023
The physicochemical composition of the used waste clay adsorbents was studied to justify the possibility of obtaining other silicate new products, and it was found that they did not differ from the original ones.
