Natural and modified zeolites (0.5-1.0 mm) from the Tasajera deposit in Cuba were used to enhance the anaerobic digestion process of synthetic substrates. Natural zeolites were modified by ionic exchange and by adsorption with nickel, cobalt and magnesium. The experiments were carried out by using an inoculum from a full-scale anaerobic reactor treating winery wastewater. Modified natural zeoli...

The photocatalytic degradation of methylene blue was investigated with TiO2 and Fe2O3 nanoparticles supported on natural zeolite. The synthesized photocatalyst was characterized by XRD, XRF, FT-IR, EDX, FE-SEM, and BET analyses. The results of XRD, FT-IR, and EDX confirmed the successful loading of Fe3+ doped TiO2 nanoparticles on natural zeolite. Further, the FE-SEM results confirmed the depos...

Background and purpose: Adsorption processes are widely used in removing pollutants from waste waters, particularly those that are not easily biodegradable such as dyes. In this study natural zeolite, which is easily found in many places, was used as a low-cost adsorbent for removal of dye from effluents. Materials and methods: Adsorption of Azo dyes including two basic and one reactive (React...
