In response to the problems of limited adsorption capacity and susceptibility to interference from ions in the existing seawater uranium extraction hydrogel materials, a novel composite hydrogel adsorbent, chitosan/imidazole crosslinked polyamidoxime hydrogel (CS/PAO@IA) was developed. This material is based on chitosan as the three-dimensional network framework and imidazole-2-formaldehyde as the chemical crosslinking agent. Through hydrogen bond effects and Schiff base reactions, a flexible and strong three-dimensional network was constructed. The correctness of the synthesized material structure was verified by systematic characterization methods, and the microscopic morphology of the material surface and the composition and valence state changes of the elements on the surface after uranium adsorption were analyzed. The uranium adsorption performance and ion selectivity of the material were tested separately. The results show that the material has good adsorption selectivity for uranyl ions in the spiked seawater with uranium mass concentration of 3.3 mg/L, and the uranium adsorption capacity is up to 18.13 mg/g. This study can provide a new idea for the development of efficient, stable and multifunctional hydrogel materials for uranium extraction from seawater.

针对现有海水提铀水凝胶材料存在吸附容量有限及易受干扰离子影响等问题，研制了一种新型复合水凝胶吸附材料——壳聚糖/咪唑交联偕胺肟水凝胶（CS/PAO@IA）。该材料以壳聚糖为三维网络骨架、咪唑-2-甲醛为化学交联剂，通过氢键效应和希夫碱反应构建了兼具刚性与柔性的三维网络。利用多种表征方法验证了该材料的结构正确性，分析了材料表面的微观样貌及材料吸附铀前、后表面元素的组成及价态变化。系统测试了CS/PAO@IA材料对铀的吸附性能与离子选择性能。结果表明；在铀质量浓度为3.3 mg/L的加标海水中，该材料对铀酰离子具有良好的吸附选择性，铀吸附容量最高可达18.13 mg/g。该研究可为开发高效、稳定、多功能的海水提铀水凝胶材料提供一种新思路。

针对现有海水提铀水凝胶材料存在吸附容量有限及易受干扰离子影响等问题，研制了一种新型复合水凝胶吸附材料——壳聚糖/咪唑交联偕胺肟水凝胶（CS/PAO@IA）。该材料以壳聚糖为三维网络骨架、咪唑-2-甲醛为化学交联剂，通过氢键效应和希夫碱反应构建了兼具刚性与柔性的三维网络。利用多种表征方法验证了该材料的结构正确性，分析了材料表面的微观样貌及材料吸附铀前、后表面元素的组成及价态变化。系统测试了CS/PAO@IA材料对铀的吸附性能与离子选择性能。结果表明；在铀质量浓度为3.3 mg/L的加标海水中，该材料对铀酰离子具有良好的吸附选择性，铀吸附容量最高可达18.13 mg/g。该研究可为开发高效、稳定、多功能的海水提铀水凝胶材料提供一种新思路。

In response to the problems of limited adsorption capacity and susceptibility to interference from ions in the existing seawater uranium extraction hydrogel materials, a novel composite hydrogel adsorbent, chitosan/imidazole crosslinked polyamidoxime hydrogel (CS/PAO@IA) was developed. This material is based on chitosan as the three-dimensional network framework and imidazole-2-formaldehyde as the chemical crosslinking agent. Through hydrogen bond effects and Schiff base reactions, a flexible and strong three-dimensional network was constructed. The correctness of the synthesized material structure was verified by systematic characterization methods, and the microscopic morphology of the material surface and the composition and valence state changes of the elements on the surface after uranium adsorption were analyzed. The uranium adsorption performance and ion selectivity of the material were tested separately. The results show that the material has good adsorption selectivity for uranyl ions in the spiked seawater with uranium mass concentration of 3.3 mg/L, and the uranium adsorption capacity is up to 18.13 mg/g. This study can provide a new idea for the development of efficient, stable and multifunctional hydrogel materials for uranium extraction from seawater.
