Water resource contamination is one of the biggest global concerns, nowadays. Among the most common oil pollutions, BTEX group (Benzene, Toluene, Ethylbenzene, and Xylene) is known to be extremely harmful to environment. The objective of this project is to develop an efficient method for the removal of oil and organic solvents from water through utilization of graphene aerogel composites as adsorbent media. To address the desirable structural and mechanical properties beside the adsorption performance, we utilized cellulosic materials to use in the composition. Thus, cellulose fibers extracted from waste papers and cellulose nanocrystals (CNC) were chosen to incorporate in the structure of graphene aerogel. A tailored mild chemical reduction has been exploited as the synthesis route. The kinetics and thermodynamics of adsorption process have been studied to understand the adsorption mechanism. The standard test methods were performed to evaluate the adsorption performance of synthesized samples in different conditions, which showed promising results for further investigations.
