| 概要 |
The great East Japan Earthquake in 2011 triggered the Fukushima Daiichi nuclear power plant accident. Large amount of cesium was released into the environment following this severe accident. Therefore..., this research work evaluated the applicability of nano-Fe/Cu particles for the removal of cesium from contaminated waters for the first time. Cesium removal was investigated using batch technique with respect to initial cesium concentration, contact time, temperature, pH, competing cations and dosage of nanoparticles. The results showed that nano-Fe/Cu particles demonstrated 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 study proved the potential utility of the nano-Fe/Cu particles as a promising adsorbent for the treatment of waters containing cesium.続きを見る
