Synthesis and application of functionalized Graphene oxide-silica with chitosan for removal of Cd II fromaqueous solution

The functionalized graphene oxide by silica and chitosan helped to prepared an adsorbent with high adsorption potential for removing cadmium(II). In this study, the adsorbent was synthesized and the batch system of adsorption method was examined to find the potential of the new adsorbent with the va...
