文摘

Copper hexacyanoferrate was imbued on pores of synthetic zeolite and the formation of needle shaped copper hexacyanoferrate microcrystals was confirmed by XRD and SEM. Batch equilibrations showed that the sorbent has good affinity for Cs and Sr which was further confirmed from column studies. It is established that a substantial amount (>8000 bed volumes) of low level waste contaminated with 137Cs and 90Sr can be treated in fixed bed column. The sorbent, owing to its low cost, simple preparation process and excellent 137Cs and 90Sr removal performance, is expected to find wide spread application in nuclear industry.
