Degradation Of Methyl Orange By Fenton Reaction Using Cual Layered Double Hydroxide/Mgo2 Composite Catalyst Under Dark Condition

Abstract

Water Pollution Due To Organic Dyes Has Been A Global Issue. Because Dyes Own Stability And Able To Soluble In Aqueous Media. As A Result, Dyes Stay For Prolonged Time While Water Gets Polluted With Such Kinds Of Effluents. In Order To Minimize The Amount Of Effluent In The Polluted Water, Enormous Methods Have Been Proposed. In Typical, Fenton Reaction Has Been Used. However, The Sludge Formation Under Iron Based Fenton, Dependent On Light Irradiation And The Need Of Acidic Media Limits Its Application. In This Report, Cual-Layered Double Hydroxide/Mgo2 Composite Was Synthesized Through In-Situ Growth Of Magnesium Peroxide On The Ldh Sheet. Profoundly, It Has Performed Well Over Wide Ph Range As Well Under Dark Environment Which In Turn Minimized The Requirement Of Light Irradiation. In This Case Unlike The Conventional Fenton Process, There Was No Difficulty In Transporting And Handling Of Peroxide Since Generating H2o2 Through In-Situ Way. As-Synthesized Powders Were Characterized And Performances Were Evaluated For Methyl Orange(Mo) Dye Degradation At Room Temperature. X-Ray Powder Diffractometer (Xrd), Scanning Electron Microscope (Sem), And Fourier-Transform Infrared Spectroscopy (Ftir) Were Used For Characterization. The Catalytic Activity Of Cual-Ldh, Mgo2, Cual-Ldh/ Mgo2 -7, Cual-Ldh/Mgo2 -10 And Cual-Ldh/ Mgo2 -13 Were Investigated For The Degradation Of Methyl Orange(Mo) Under Dark. Among Them, Cual-Ldh/ Mgo2 -10 Shows Excellent Fenton Like Reaction Under Neutral Condition At Which 97% Of Mo Was Degraded With In 100min. While 98% Of MoRemoval Was Achieved At Acidic Ph Within 60 Min. The Higher Degradation Efficiency By This Particular Composite Is Attributed To The Presence Of Copper Along With The Generated Hydrogen Peroxide To Run Fenton Process. Trapping Experiment Values Also Confirmed That Both Copper And Hydroxyl Radical Were An Active Species For The Degradation Of Mo. Moreover, The Catalyst Can Also Be Able To Use For Several Cycles With A Minimum Loss Of Activity. In General, The Result Of This Study Suggests That Cual-Ldhmgo2-10 Composite Is An Option For The Conventional Fenton Based Degradation Of Mo Under Dark Environment.
