Resin 201*7 was used to extract and remove vanadium from vanadium waste liquid (VWL). More than 99% of vanadium was adsorbed from the VWL under the condition of resin dosage of 1.6 g/L, pH value of 6.0-8.0, temperature of 40 °C and adsorption time of 20 min. More than 99% of vanadium could be separated from other impurity ions in the VWL. The pure resin 201*7 and loaded resin were analyzed by infrared spectroscopy. The result shows that the resin 201*7 could selectively adsorb vanadium from the VWL. The adsorption process was analyzed with adsorption kinetics and adsorption isotherm curve. The adsorption process was more fitted with pseudo-second adsorption kinetic model and the adsorption isotherm was according to Langmuir isotherm model, respectively.
