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.
