The volume reduction and subsequent solidification of soluble radionuclides have been known as the major challenges in global radioactive water management, with the urgent needs for new technology development. Thus, a novel forward osmosis (FO)-adsorption process was developed for decontamination of strontium-containing radioactive water. The FO filtration driven by the osmotic pressure difference across FO membrane was more cost- and energy-effective for pre-concentration and volume reduction of low-concentration radioactive water prior to solidification, whereas subsequent adsorption with a novel adsorbent offered an effective mean for high-efficiency fixation of soluble radioactive on adsorbent. Results showed that the FO unit in the proposed integrated process could lead to a concentration factor of 10, with 90% of water volume reduction. The concentrated stream with a smaller volume from FO was further treated through adsorption of Sr²⁺ by nanostructured layered sodium vanadosilicate which had an excellent adsorption capacity of 174.3 mg Sr²⁺/g. It was found that 96.8–99.9% of soluble Sr²⁺ in FO concentrate could be removed by adsorption within several seconds. As the result, an excellent solidification of Sr²⁺ with an ultimate concentration factor of 1000 was achieved in the proposed novel integrated FO-adsorption process. These clearly demonstrated that this process would offer an environmentally sustainable and economically viable engineering solution for high-efficiency decontamination of Sr²⁺-containing radioactive water.

随着新技术开发的迫切需求，可溶性放射性核素的减少体积和随后的固化已被视为全球放射性水管理中的主要挑战。因此，开发了一种新颖的正向渗透（FO）吸附工艺来净化含锶放射性水。由FO膜上的渗透压差驱动的FO过滤对于固化前低浓度放射性水的预浓缩和体积减小具有更高的成本和能源效益，而随后使用新型吸附剂的吸附则提供了有效的方法来进行高浓度的过滤。放射性固定在吸附剂上的效率高。结果表明，所提出的集成工艺中的FO单元可导致10的浓缩系数，并减少90％的水量。纳米结构层状钒硅酸钠制成的²⁺具有极好的吸附能力，为174.3 mg Sr ²⁺ / g。发现在FO浓缩液中可吸收的96.8–99.9％的可溶性Sr ²⁺可在几秒钟内被吸附去除。结果，在提出的新型集成式FO吸附过程中，最终浓度因子为1000的Sr ²⁺具有出色的固化性。这些清楚地表明，该方法将为含Sr ²⁺的放射性水的高效净化提供环境可持续和经济可行的工程解决方案。
