AB  - The present study focuses on clinoptilolite (CLI)-rich natural zeolitic tuffs and their photocatalytic activity in the degradation of cationic organic dyes. CLI from different regions was tested in the photocatalytic degradation of methylene blue (MB) as a model cationic dye. The photocatalytic tests were performed at room temperature and atmospheric pressure under visible light irradiation. For all the CLI samples, the highest activity was observed at pH = 6. Total MB degradation varied between 70 and 91% (C0 = 10 mg dm–3, 0.2 g dm–3 of photocatalyst, during 300 min). It is suggested that the presence of Fe species in the studied tuffs is responsible for the photocatalytic activity. The activity increases linearly with the Fe content in the tuffs. The MB photodegradation follows the Langmuir–Hinshelwood kinetic model. The recyclability tests showed good stability and efficiency of the photocatalyst. The degradation rate decreased from 91 to 69% during three reaction cycles, indicating a promising potential of natural zeolites in the treatment of textile industry wastewater.

AB  - Due to their structural complexity, chemical stability, and toxicity, organic dyes mostly used in the textile industry, cause serious environmental problems. Advanced Oxidation Processes (AOPs) currently appear to offer a high potential for complete degradation of organic dyes. The present work is focused on natural clinoptilolite (CLI) and its unusual photocatalytic activity. CLI from different regions were studied as photocatalysts in the photodegradation of methylene blue (MB) as a model cationic dye under visible light at room temperature and atmospheric pressure at different pH. For all CLI samples at pH = 6, the total degradation degree of MB varied from 74 to 88 %, thus indicating a high photocatalytic activity of CLI.
