摘　　要： 介绍了吸附法去除水体中放射性碘的研究进展与应用现状,对技术特点进行了总结和分析。叙述了活性炭、天然无机材料、纳米材料、离子交换树脂和生物吸附材料处理放射性碘污染废水的研究进展。为寻求性能优异、选择性强、稳定性好的新型吸附材料用于水体中放射性碘的去除,依然是未来研究的方向;需要采用更为先进的技术,深入研究吸附机理;积极研发与这些吸附材料相适应的成套水处理工艺和设备,或与现有的成熟的放射性废水处理工艺相结合,扩大吸附材料在水体中放射性碘处理中的应用范围,提高应用效率。 The research progress and application status of radioactive iodine removal in water by adsorption process was reviewed, and the technical characteristics were summarized and analyzed in this paper. The materials for wastewater containing radioactive iodine treatment such as activated carbon, natural inorganic materials, nanomaterials, ion exchange resin and biological adsorbent were discussed. Explore new type adsorbent material with good performance, strong selectivity and good stability to removal radioactive iodine in water will be the direction of the future research. And advanced technology should be used to research the adsorption mechanism, complete water treatment process and equipment which suitable with the adsorbent materials should be researched and developed, and combined with existing, mature radioactive wastewater treatment processes to expand the applied range of adsorbent materials for radioactive iodine treatment in water and improve the application efficiency.
