Abstract

The aim of this work is to create reduced graphene oxide from graphene oxide synthesized by the Tour method and then reduce it using ascorbic acid. We used field emission scanning electron microscopy (FESEM), Fourier transform infrared (FTIR), and Raman spectroscopy to examine and measure the data. In the current study, we used RGO to adsorp and remove methyl orange dye (MO). We investigated the effects of pH and ionic density on the dye removal process, as well as the surface weight of the adsorbent and the length of time the dye remained in contact with RGO. We considered the temperature, isotherms, and adsorption kinetics and came to some final conclusions.
