摘　　要：铀废水的处理是绿色利用核能的关键,而处理废水后的树脂材料具有放射性,为后续的处置带来困扰。以淀粉、明胶为基体,SiO_(2)微球为模板,炭化后,KMnO_(4)氧化制备了一种孔径可控、环保无毒的铀吸附材料。研究结果表明,在pH=6.00,25℃,固液比1 g/L,24 h的条件下,U(VI)吸附率可达到92.98%。在不同的掺铀真实水样中均有较好的吸附效果。The treatment of uranium wastewater is the key in the process of green usage of nuclear energy and the resin material after the treatment of wastewater is also plagued with radioactive disposal.A uranium adsorbent material with controllable pore size and environmentally friendly and non-toxicity was prepared by carbonization using starch and gelatin as substrates and SiO_(2)microspheres as templates,which were oxidized using KMnO_(4).The results showed that the adsorption rate of U(VI)solution could reach 92.98%under the conditions of pH=6.00,temperature of 25℃,solid-liquid ratio of 1 g/L,and adsorption time of 24 h.It has good adsorption capacity in different real water samples doped with uranium.
