چکیده:

In recent years, synthesis of inorganic materials with specific size and morphology has attracted significant attention due to their possible use in different fields [1-2].ZnO is a polar inorganic crystalline material with many applications due to its unique combination of interesting properties. Till now, many methods have been developed to synthesize zinc oxide nanocrystals. The precipitation method has been proven to be a useful technique to obtain materials with interesting properties [3-4]. In photocatalysis systems a combination of semiconductors (such as TiO2, ZnO, Fe2O3, CdS, ZnS) and UV or Visible lights can be used. Various attempts have been made to increase of photocatalytic activity of semiconductors. The objective of the present work is to study the photocatalytic activity of prepared ZnO at nanoscales under different condition in the removal of C.I. Acid Red 27(AR27) as a model contaminant from textile industry
