摘要以废丙纶和研磨的海藻为原料，采用反相沉淀法制备了牙叶马尾藻吸附藻类聚合物复合膜。对其废液中铀和钍的吸附进行了评价。结果表明，在短时间内，该树脂对U和Th的吸附容量分别为62和59.4mgg−1。吸附实验数据表明，两种金属离子均符合Langmuir等温线和准二级动力学模型。复合膜的可重复使用性表明了其在废液中脱铀和Th的稳定性和有效性。
AbstractNovel adsorption Algal polymer composite membrane composed of acrylic fiber wastes and grinded marine algae;Sargassum dentifoliumwas newly prepared using inversion precipitation technique. The adsorption of uranium and thorium from their waste solution was evaluated. The results indicated that the sorption capacities for U and Th were 62 and 59.4 (mg g−1), respectively, within short time. Adsorption experimental data demonstrated that both metal ions were well fitting with Langmuir isotherm and pseudo-second order kinetics model. The reusability of the composite membrane indicates the stability and efficiency of it in U and Th removal from waste solution.Graphic abstract
