چکیده

Color is one of the permanent features of surface water. Industrial effluents from textile and dyeing and other operations associated with the streams and rivers of the treatment process has become essential. Many of the chemicals used in the textile industry is causing environmental and health problems. Environmental problems associated with pollution caused by the discharge of untreated water is investigating [1]. Nitrophenols, toxic, inhibitory and biorefractory organic compounds, are extensively use in chemical industries for the manufacture of pesticides, dyes and pharmaceuticals [2].One of the methods to remove contaminants affordable optical degradation process is carried out using heterogeneous catalysts. During recent years the use of recyclable heterogeneous catalyst considerable importance due to the environmental aspects of economic and industry. Clay, silica alumina and other platforms that are common examples of heterogeneous catalysts are widely used [3]. Zeolite, with unique micropore structure, high thermal stability and high acidity, is widely applied as adsorbent, catalyst or catalyst supports in lots of fields, such as basic petrochemistry, oil refining and fine chemicals synthesis [4]. In this post-synthesis using metallic iron and cerium encapsulated within the zeolite and its photocatalytic activity will be examined. 4-nitro phenol photocatalytic system for optical degradation will be tested and it will be removed by the technique of spectroscopy [5].
