Resin 2017 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 2017 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.
树脂 2017 用于从钒废液（VWL）中提取和去除钒。在树脂用量为 1.6 g/L、pH 值为 6.0-8.0、温度为 40°C 和吸附时间为 20 min 的条件下，超过 99%的钒从 VWL 中被吸附。超过 99%的钒可以从 VWL 中的其他杂质离子中分离出来。用红外光谱法对纯树脂 2017 和负载树脂进行了分析。结果表明，树脂 201*7 可以从 VWL 中选择性地吸附钒。用吸附动力学和吸附等温线曲线对吸附过程进行了分析。吸附过程更符合拟二级吸附动力学模型，吸附等温线符合朗缪尔等温线模型，分别。
