Abstract

The great East Japan Earthquake occurred in 2011 and seriously damaged Fukushima Daiichi Nuclear Power Plant. Large amounts of cesium was released into the environment following this accident. Therefore, this study for the first time assessed the applicability of nanosccale zero valent iron (nZVI) for the removal of cesium from aqueous solutions. The removal of cesium was investigated in a batch system with respect to initial cesium concentration, contact time, pH, temperature, competing cations and dosage of nanoparticles. The obtained results showed that nZVI displayed effective performance for removal of cesium. The removal efficiency exceeded 99% at initial cesium concentration of 1 mg/L and 1 g/L dose. The removal of cesium was largely depending on the solution pH and temperature. The current work proved the potential utility of the nZVI in the treatment of cesium contaminated water generated after the Fukushima nuclear accident.
