Radioactive cesium removal from ash-washing solution

2016-5-1  The effectiveness of K 2 Zn 3 [Fe(CN) 6] 2 (KZnHCF) for the radioactive cesium (R-Cs) decontamination from wood ash extract is studied. Because the ash-washing solution is of high pH and high K +-concentration, adsorbent with high pH tolerance and selectivity for Cs + over coexistent K + is required. For this purpose, we evaluated the effectiveness of KZnHCF, Prussian blue (PB), and zeolite.
