Publisher: | Institute of Physics Publishing | Abstract: | In this paper, we investigated the superiotires of carbon-based nanomaterial polymer inclusion membrane (PIM-GO) against to polymer inclusion membrane and removed Cr(VI), a highly toxic element typically used in chromate conversion coating in the plating industry, from the chrome plating water by using a PIM-GO modified with graphene oxide (GO), which strengthens the mechanical structure and permeability of PIMs. We performed experiments to investigate the membrance performance and structural ability ofthe PIM-GO, and lastly compared its performance to that of the PIM. We observed the PIM-GO's high selectivity and recovery (96.83%) in the removal of Cr(VI). GO added to the membrane structure caused a visible increase in the rate constant, permeability and flux.The PIM-GO affords opportunities to work with a wider range of pH levels, changes of which in membrane-based experiments with unmodified PIM shave caused significant decreases in flux and permeability. The ease of use, applicability, high permeability of the PIM-GO at high temperatures afford significant advantages over the unmodified membrane as well. The results of this study can aid the development of next-generation membranes with increased mechanical stability, the resistance to multilayered GO membranes, and the use of the membranes in industrial applications. Moreover, the high transport efficiency of the PIM-GO at temperatures exceeding room temperature is evidence of the improved thermal stability of the PIM-GO. In effect, our findings can inform the production of new membranes with increased mechanical stability, membrane lifetime, and usability in industrial applications. © 2020 The Electrochemical Society ("ECS").
