Photodegradation of congo red in aqueous solution by using advanced oxidation process (aops) technique / Ninna Sakina Azman

Congo Red (CR) is one of the complicated azo dyes which consist of three N=N double bonds. Significantly, to degrade the dyes contained in the waste water, it is necessary to choose the best method. The method that had been used in this project is advanced oxidation process or best known as AOPs met...
