The removal of Cr(VI) through graphane oxide based polymer inclusion membrane

Abstract

In this study, graphane oxide which is the new generation carbon-based nanomaterials were added to the structure of polymer inclusion membrane (GO/PIM) and Cr(VI) metal, which is highly toxic to the environment, was removed, with this new generation synthesized membrane from the donor phase to the acceptor phase. The high toxicity and carcinogenicity of Cr(VI) make this compound one of the most alarming and urgent metals that must be controlled. Graphane oxide which was added to the membrane structure caused a visible increase in the kinetic results by affecting the rate constant, permeability, flux and recovery factor. The effect of plasticizer was investigated in the modified membrane and the removal of Cr(VI) ions was obtained with highly selective and a high recovery value of 99.044%. In the direction of the parameters were examined, GO/PIM offers us the opportunity to work in a wider range of pHs. The ease of use, applicability and high permeability and flux values of the modified membrane at high temperatures provide a significant advantage. The high transport efficiency of the GO/PIM membrane at temperatures above room temperature is an evidence of how far the thermal stability of the modified membrane has improved. The present study presents a very attractive, appropriate and innovative approach to GO's new generation of water treatment technologies.
