Photocatalytic activity of Fe(III)-loaded clinoptilolite in the degradation of methylene blue as a model pollutant

Abstract

Due to structural complexity and toxicity of organic dyes their presence in water body causes usually serious environmental problems. Advanced Oxidation Processes (AOPs) have been recognized as effective methods for a complete degradation of organic dyes. In this study, Serbian natural zeolite (clinoptilolite) loaded with Fe(III) was used for the preparation of a photocatalyst and its catalytic activity was tested in the photodegradation of methylene blue (MB) as a model cationic dye under visible light at room temperature and atmospheric pressure. It is showed that the prepared Fe(III)-containing clinoptilolite (FeZ) can be used as active and recyclable photocatalyst in degradation of MB.
