本发明提供了一种新型功能化纤维的制备及使用方法：以聚丙烯腈纤维为基体材料，预处理后采用水热法将氨基接枝到基体材料上，制备新型功能化纤维（编号为XKXW‑IV）。本发明采用的材料制备方法简单，官能团接枝率较高（≥74.7%），XKXW‑IV性能稳定，亲水性好，吸附容量较高，可重复利用，具有一定的耐有机物性能，在优化条件下对铀的吸附量高达492.6 mg/g。针对常规有机物（四氢糠醇、PVA、尿素等）、阴离子（NO3‑、SO42‑、Cl‑等）及阳离子（Pb2+、Cu2+、Ni2+、Sr2+等）共存的复杂含铀废水，本发明制备的XKXW‑IV对铀表现出较好的选择性（Kd≥857.5 L g‑1），处理真实高温气冷堆燃料元件核芯制备工艺废水时铀去除率可达99.7%。因此，XKXW‑IV在核燃料循环过程产生的复杂含铀废水处理方面具有较好的应用前景。
