Irconium Sulfate Precipitating

The conditions for precipitating barium as BaSCU and radium coprecipitation with BaSOfrom spent brine were also established. The amount of sulfate that must be added relative to the amount of barium in the brine is a function of the barium concentration and the TDS of the brine. If no barium is present in the spent brine, BaCU or BaCC3
