Abstract

With the increasing technological development, the problem of hydrocarbon pollution has become one of the urgent problems of our current era. Many techniques have been proposed and applied to address this phenomenon, including the use of polymer-based nanocomposites. This study involved the preparation of a few wrinkled layers of graphene oxide from waste pencils (wp-GO) as proved by the High-resolution transmission electron microscopy HRTEM image. Besides, magnetic iron oxide nanoparticles were synthesized and showed superparamagnetic properties due to the magnetic properties of 40 emu/g saturation magnetization and close to zero coercivity, the structure is mostly spherical particles with a diameter of 8–10 nm. These nanomaterials were exploited as a composite along with melamine-formaldehyde polymer MF. The HRTEM results showed that the prepared wp-GO-MF composite has a stable structure with many porous. The wp-GO-MF composite was applied for several hydrocarbons adsorption. Hydrocarbons adsorption study was accomplished using benzene, toluene, m-xylene, hexane, heptane, kerosene, and diesel oil. The findings revealed that the wp-GO-MF composite performs the highest sorption capacity (Qe) for kerosene at 71 g g–1. Adsorption capacity was maintained at around 90% for the hydrocarbons up to 10 absorption cycles. Therefore, it can be concluded that the wp-GO-MF composite successfully showed an excellent sorption capacity for all tested hydrocarbons with superb recycle performance.
