Abstract

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 $^{+}$ $^{+}$ from the solution in a wide range of pH. The maximum adsorption capacity reaches 131mgg $^{- 1}$ $^{- 1}$ . 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 $^{+}$ $^{+}$ removal from radioactive wastewater.
