چکیده:

Zeolites have been increasingly used in various application areas such as industry, agriculture,
environmental protection, and even medicine. More than 50 natural species of zeolites have been recognized,
and clinoptilolite, erionite, chabazite, heulandite, mordenite, stilbit and philipsite are the most well-known.
The most common for agricultural applications is clinoptilolite since it has high absorption, cation exchange,
catalysis and dehydration capacities. Zeolites are, therefore, used as a promoter for better plant growth by
improving the value of fertilizers; retaining valuable nitrogen and improving the quality of resulting manures
and sludge. They can also be used as a molecular sieve or filter medium.
