title: Supporting of coupled silver halides onto clinoptilolite nanoparticles as simple method for increasing their photocatalytic activity in heterogeneous photodegradation of mixture of 4-methoxy aniline and 4-chloro-3-nitro aniline.
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).
