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).
通过将AgX（X = I、Br、Cl）分散在纳米斜发沸石颗粒（NCP）中来合成新型光催化剂。所获得的复合材料（AgX-NCP）用于在汞灯照射下对4-甲氧基苯胺和4-氯-3-硝基苯胺的水性混合物进行光降解。所有样品均通过傅里叶变换红外光谱（FT-IR）、X射线衍射（XRD）、漫反射光谱（DRS）和透射电子显微镜（TEM）进行表征。研究了诸如AgX负载量、光催化剂用量、初始pH值和浓度等操作参数对光矿化的影响。通过紫外可见光谱监测降解程度，并通过化学需氧量（COD）对结果进行确认。
