  7. Abstract:
  8. consumption of which (especially azo dyes) have been increasing nowadays, causing the increase of textile wastewaters. Usually, these wastewaters contain an immense number of dyes, and if these dyes release in the environment especially in waters, they cause some problems, such as the change of watercolor as well as taste, and affect creatures' lives severely. Moreover, If the dyes are left untreated in aquatic ecosystems, they can remain in the environment for a very long time, resulting in harmful and irreversible effects. Azo dyes are classified as mono, di-, three, azo dyes due to their bonds. Because dyes are increasingly used, nowadays, different methods are developed for the treatment of dye wastewaters; for example, physical methods, chemical, and biological methods. In this thesis, MIL-88A(Fe) was synthesized and characterized by FTIR, XRD, SEM, TEM, BET, PL and DRS. Photocatalytic activity of the photocatalysts for degradation of Rhodamine B (RhB), as contaminants, in aqueous solution under LED light are investigated. The parameters which affect the degradation of the RhB dye such as nanoporous photocatalyst content, dye concentration, and pH in the dye solution were studied. Eventually, zero, first and second kinetic reactions were proposed
