The most economically significant clinoptilolite-tuff source of the European Union is the volcanogenic-sedimentary deposit in the East Slovak basin with an estimated 150 million tons of clinoptilolite-tuff. The Slovakian clinoptilolite-tuff comprises a rhyolitic composition and is comparable to volcanic rocks in the central segment of...
1.) Definition The name “zeolite” goes back to the Swede Axel Fredrick von Cronstedt, who created this name in 1756 which means “boiling stone” (the Greek word “zeos” means “boiling” and the word “lithos” means “stone”). Zeolites are hydrated alumosilicates of the alkaline and alkaline-earth metals [1]. 2.)...
Clinoptilolite-tuff results from volcanic eruptions more than 15 million years ago, a time when the continents drifted to their actual position and plants as animals in their present form evolved. Mineralogically, clinoptilolite belongs to the zeolite family, which itself consists of more than 40 members of...
Abstract: The occurrence of health-relevant contaminants in water has become a severe global problem. For treating heavy-metal-polluted water, the use of zeolite materials has been extended over the last decades, due to their excellent features of high ion exchange capacity and absorbency. The aim of...
Heavy metals are elements that are typically solid, malleable, are shiny when polished and conduct electricity and heat well. Heavy metals are at least 5 times as dense as water and have a high atomic weight. Five heavy metals are known to cause serious health...
