▎ 摘　　要

Humanity is facing the biggest hazard in the form of systematic pollution of environment. Significant dwindling resources is a sign of rapid population explosion. Due to increasing human population, the burden on environment is also increasing exponentially leaving serious concerns about greenhouse gases induced climate change, energy security as well as the air, land and water quality deterioration. These concerns are driving the development of alternate energy solutions and to modify fuels with high sulfur and nitrogen content to mitigate cleaner fuel crises in the developing countries like Pakistan. To this end, Graphene oxide-GO (synthesized from refused dry cell batteries) and Magnetic Graphene oxide-MGO based ionic liquids (ILs) were synthesized and fabricated with cellulose acetate (CA) for their potential applications in desulfurization of fuel. Synthesized ILs were characterized by different techniques such as Attenuated Total Reflectance (ATR-FTIR), Thermogravimetric Analysis (TGA), X-ray Diffraction (XRD) and Cyclic Voltammetry (CV). Close batch experiments were designed to evaluate the desulfurization and adsorption capabilities of prepared liquids under varying parameters. Moreover, HPLC and UV-Visible spectrophotometer were used to determine the reduction of thiophene peaks and extent of desulfurization (%R > 98.9 % and 91 % for Model fuel and Crude fuel, respectively). The proposed study offers an economical and eco-friendly material that have open up a wider application window and owing to the surface modifications these hybrid materials with multi-functional groups are expected to reduce the pollution load from multi-compartment simultaneously.
