Removal of cesium from a salty, aqueous waste with sodium tetraphenyl boron

Conference ·
OSTI ID:5362950
; ; ;

A process for the coprecipitation of cesium-137 with potassium, using sodium tetraphenyl boron, from a salty, aqueous, low-level radwaste was developed and successfully conducted. Potential treatments for cesium removal from the waste were first evaluated. As a result of this evaluation, which compared a number of factors including cost, safety, equipment availability, and decontamination, physical separation techniques and adsorbents were eliminated. Two chemical treatments involving sodium tetraphenyl boron and copper ferrocyanide were further tested. Treatment with sodium tetraphenyl boron was chosen and successfully reduced the cesium-137 concentration in the supernatant of the waste from 570 to 4 counts/min/ml.
