Natural purified mordenite from Palmarito de Cauto (ZP) deposit, Cuba, was subjected to a hydrothermal ion exchange process in acid medium with Fe2+ or Fe3+ salts (Fe2+ZP and Fe3+ZP). The set of samples was characterized regarding their textural prop

Copper-silver bimetallic system supported on natural clinoptilolite from Tasajeras deposit (Cuba) was studied. Bimetallic samples were prepared by simultaneous ion exchange, and reduced in a wide temperature range in a hydrogen flow. The main goal of

Clinoptilolite is a widely used natural zeolite due to its abundance in nature. The present work discusses the characteristics of silver modified clinoptilolites (natural and synthetic) containing silver in different states. The results obtained by t

The Fe 2+ -containing natural clinoptilolite (FZ) was studied by X-ray diffraction, thermal analysis, infrared (diffuse reflectance), dielectric, and Mossbauer spectroscopies. The presence of FeSO 4 occluded in the cavities of the clinoptilolite was

The development of a zeolitic active principle called FZ that shows a high selectivity for glucose adsorption is described. FZ has been obtained by hydrothermal transformation of natural purified clinoptilolite. This principle has been physically and
