THE THERMAL DEHYDRATION OF NATURAL ZEOLITES
Investigation of zeolites by heat treatment dates back to the middle of the 18th century. CRONSTEDT (1756) at that time noted that on heating certain minerals seemed to melt and boil simultaneously with an intense production of water vapour. He therefore called these minerals zeolites, a combination of the Greek words zein, to boil, and lithos ...

2. Natural zeolitic materials and environmental remediation. The application of natural zeolites to the environmental remediation is mainly based on their ion-exchange properties . It is also well-known that ion-exchange in the case of zeolites takes place among cations and only their modification can provide them with anion sorption properties.
