Abstract

Novel photocatalyts were synthesized by dispersion of AgX (X=I, Br, Cl) in nano clinoptilolite particles (NCP). The obtained composites (AgX-NCP) were used for the photodegrading of aqueous mixture of 4-methoxy aniline and 4-chloro-3-nitroaniline under Hg lamp irradiation. All samples were characterized by FT-IR, XRD, DRS and TEM. The effects of operational parameters such as: the loaded extent of AgX, the amount of photocatalyst, initial pH and concentration on photo mineralization were studied. The degradation extent was monitored by UV–Vis spectroscopy and the results were confirmed by the chemical oxygen demand (COD).
