摘要：

Liquid low-level radioactive waste (LLLW) and slightly contaminated process wastewater at Oak Ridge National Laboratory has been tested for removal of Cs-137 using several transition-metal hexacyanoferrate compounds. The method being developed is scavenging precipitation, in which ion exchange particles are mixed with the solutions and allowed to settle. Decontamination factors of 35 for simulated LLLW and 12 for process wastewater were achieved.
