一种去除废水中铬离子的改性碳纳米管的制备方法
摘要：
本发明涉及一种去除废水中铬离子的改性碳纳米管的制备方法，步骤包括：(1)改性碳纳米管的预处理；（2）聚多巴胺改性碳纳米管的制备；（3）利用改性碳纳米管从废水中吸附铬离子；（4）测试吸附前后铬离子的吸附量，评价改性碳纳米管的吸附性能。该方法简单、高效，适用于快速去除废水中的重金属铬离子。
摘要（英）：

The invention relates to a preparation method of a modified carbon nanotube for removing chromium ions in wastewater. The preparation method comprises following steps: (1) preprocessing a modified carbon nanotube; (2) preparing a polydopamine modified carbon nanotube; (3) using the modified carbon nanotube to adsorb chromium ions from wastewater; and (4) measuring the amount of the adsorbed chromium ions before/after adsorption, and evaluating the adsorption performance of the modified carbon nanotube. The preparation method is simple and efficient, and the modified carbon nanotube is used toremove heavy metal ions (chromium ions) in wastewater rapidly.
