通过便捷的一锅伽马辐射路线成功合成了六氰基铁酸钾铁/聚丙烯酰胺纳米杂化水凝胶（PB/PAM-gel）。所制备的PB/PAM-gel具有致密的内部三维多孔结构和分散良好的PB纳米线，表现出良好的弹性和优异的溶胀性能。吸附实验表明，PB/PAM-gel可以在较宽的pH范围内快速、选择性地从溶液中吸附Cs[式：见正文]。最大吸附容量达到131[式：见文字]mg[式：见文字]g[式：见文字]。这种纳米杂化水凝胶非常稳定，吸附后很容易从溶液中分离出来。它可以作为潜在的吸附剂用于去除放射性废水中的Cs[式：见正文]。
Potassium iron hexacyanoferrate/polyacrylamide nanohybrid hydrogel (PB/PAM-gel) was successfully synthesized via a convenient one-pot gamma radiation route. The as-prepared PB/PAM-gel has compact internal three-dimensional porous structures with well-dispersed PB nanowires, which exhibit good elasticity and excellent swelling performance. The adsorption experiments reveal that the PB/PAM-gel can rapidly and selectively adsorb Cs[Formula: see text] from the solution in a wide range of pH. The maximum adsorption capacity reaches 131[Formula: see text]mg[Formula: see text]g[Formula: see text]. This nanohybrid hydrogel is very stable and can be easily separated from the solution after adsorption. It can be applied as a potential adsorbent for Cs[Formula: see text] removal from radioactive wastewater.
