Hexavalent chromium removal mechanism using conducting polymers

► Mechanism of Cr(VI) detoxification using conducting polymers has been ascertained ► Effect of various parameters on Cr(VI) detoxification has been determined ► Results demonstrated formation of Cr(III) and its subsequent adsorption on polymers ► This work has potential in selection of suitable polymer for chromium remediation ► Polyaniline and Pd-decorated PANI are recommended for future sensor applications.
