pem聽Individual chemical composition of mordenite and clinoptilolite, which are both found in zeolite rocks and acid modification effect on them have been calculated. For the purpose of this study, samples of rocks of the same deposit (village Lypcha, Transcarpatia) with different content of ...
Zeolite characterization covers the fields of chemical composition, structural identification, the distribution of tetrahedral (T) atoms, the acidity and basicity linked to the framework, and extra-framework species, the post synthesis-modifications and the presence and nature of defect groups which can...

Zeolite are crystalline microporous aluminosilicates that are used as catalysts, adsorbents and ion-exchangers [19], [20], [21]. Different surface treatments can be used to increase the ion-exchange capacity of the zeolites. The most common modifications on the surface of the zeolites are ...
Zeolite samples with different surface chemical composition were prepared from a Chilean natural zeolite. Such treatments included acid de-alumination, and thermal treatment at 400 °C and 550 °C prior to contact with ozone. Chemical modification of natural zeolite showed that the generation of new...
