Resin D201, D314 and 717 were compared for their efficiency to extract vanadium from hydrochloric acid leaching solution of red mud. The adsorption parameters were investigated in details by using the three resins. The separation characteristics and mechanism of vanadium were analyzed with infrared spectroscopy and adsorption kinetics. More than 99% of vanadium was selectively adsorbed by using resin D201 at pH value of 2.0, flow speed of 6 m(3)/h.m(3) resin, resin D314 at pH value of 3.0, flow speed of 4.8 m(3)/h.m(3) resin, and resin 717 at pH value of 5.0, flow speed of 7.92 m(3)/h.m(3) resin, respectively. The maximum loading of vanadium by using resin D201 was more than resin 717 and D314. The vibration peak of functional group on the resins increased after adsorption of vanadium from the leaching solution. The adsorption process of vanadium was according with the pseudo-second adsorption kinetic model.
