Abstract
This work aims to create a quaternary composite of reduced graphene oxide (RGO), multi-walled carbon nanotubes (MWCNTs), urea, and choline chloride by employing discrete flame deposition technology to create MWCNTs and graphene oxide in a tour method. Reduced graphene oxide was created by reduction using ascorbic acid, and the deep eutectic solvent was then synthesized. The product was characterized using several techniques, including field emission scanning electron microscopy (FESEM) and Fourier transform infrared (FTIR). In order to adsorb and eliminate the dye methyl orange (MO), the current work employed a mixture of Deeb Eutictic Solnents (DES) such as urea and choline chloride with RGO and MWCNTs. Some techniques such as: HNMR, C13 and IR tests, were used to examine the data for the eutectic solvents of urea and choline chloride. The weight of the adsorbent, the duration of contact between the dye and the composite, temperature, pH, and ionic density were among the characteristics whose effects on dye adsorption were examined. Additionally, isotherms and adsorption kinetics were investigated.
