Abstract

A new series of sorbent materials comprised of green hyper-branched polymer and reduced graphene oxide was prepared. The hyperbranched polymer was synthesized by a three-step reaction of chitosan (extracted from shrimp shells) with 2-chloroethyl amine to give three generations denoted as G1, G2, and G3 (the hyperbranched polymer). G3 was used to form four composites with reduced graphene oxide (rGO). rGO was synthesized from graphite powder by modified Hummer's Method followed by the reduction of GO with hydrazine hydrate. The composites were denoted as HBP/rGO0-2 for rGO from 0 to 2 wt % respectively. The grafting reaction was confirmed by FTIR. The morphology of the composites was monitored via the scanning electron microscopy (SEM). Other properties such as the thermal properties and the crystallinity of the prepared composites were also investigated by the thermal gravimetric analysis (TGA) and X-ray diffraction (XRD) analysis respectively. The prepared hyper branched polymer can be used as adsorbent for removal of toxic heavy metals from petroleum waste water.
