Environmentally benign biopolymer dextran was used to control the corrosion of 6061 Al alloy in 1 M HCl. The electrochemical techniques employed for the studies were potentiodynamic polarization and electrochemical impedance spectroscopy. The surface morphology was studied by scanning electron microscopy and elemental mapping was done by the energy dispersive X-ray analysis. Dextran emerged as a potential green corrosion inhibitor for the corrosion control of 6061 Al alloy in an acidic medium. It acted as mixed inhibitor, underwent physisorption and followed the Langmuir adsorption isotherm.
