Removal of arsenic v+ contaminant by Fixed Bed Column Study by Graphene Oxide Manganese Iron (GO-Mn-Fe) Nano Composite-Coated Sand

Abstract

Nowadays, nanoparticles are widely used to remove heavy metals specially arsenic. The removal of arsenic (V) has been significantly impacted by this nano material, which is a composite of manganese di iron oxide (Fe2MnO4) and monolayer sp2 hybridized graphene oxide. Iron and manganese ligand are functionalized in Graphene oxide by a robust process of one pot synthesis method. This GO-Mn-Fe nano composite has been characterized by scanning electron microscopy (SEM), atomic force microscopy (AFM), and Brunauer–Emmett–Teller (BET). Smaller size, high surface area makes this nanoparticle is more attractive for arsenic-contaminated water treatment. A fixed bed column breakthrough study was done to determine the adsorption capacity of Graphene oxide manganese iron (GO-Mn-Fe) nano composite. The arsenic (V) metalloid adsorption was examined by different breakthrough curve Adams–Bohart, Thomas and Yoon–Nelson model. The Thomas model showed the superior coefficient of determination (R2) than another model.
