A precipitation and adsorption process has been developed to remove cesium, strontium, and plutonium from water-soluble, high-level radioactive waste. Sodium tetraphenylborate precipitates cesium and sodium titanate adsorbs strontium and plutonium. The solids are separated from the decontaminated salt solution by crossflow filtration. This new process offers significant capital savings over an earlier ion exchange process for salt decontamination. Chemical and engineering studies with actual and simulated waste are reported. The effect of many variables on the decontamination factors and filter performance are defined. 3 references, 5 figures, 3 tables.
