Natural zeolites – environmental, biomedical and industrial applications
Natural zeolites are microporous hydrated aluminosilicate minerals having countless technological applications due to their unique physicochemical features such as cation exchange, selective adsorption, molecular sieving, catalysis, etc. As far as cation exchange is concerned, natural zeolites have been largely investigated for ammonia and heavy-metal removal, although modification of these minerals with long-chain cationic surfactants enhances their adsorption properties towards anions and low polar organic contaminants. In addition, they have also recently been considered as carriers of pharmaceutical-active ingredients. This session is designed to promote discussions on these topics but also on other interesting technological applications including water and wastewater treatment, soil remediation, treatment of radioactive waste, as well as application in the veterinarian, pharmaceutical and industrial sectors.
