Breakthrough curve modeling of graphene oxide aerogel packed fixed bed column for the removal of Cr(VI) from water

The extensive investigation was conducted on the performance of the laboratory-scale fixed-bed column containing graphene/polylysine aerogel as an adsorbent for the removal of Cr(VI). The effect of important column design parameters on the performance of the column bed was investigated. High bed height, low influent flow rate, and high influent Cr(VI) concentration were found to be the better condition for the adsorption of Cr(VI). The effect of...
