Simultaneous Ion-Exchange Removal of Radioactive Cesium and Strontium Ions from Sewage in Electric Field
It is described the technique of calculating the ion-exchange column with a fixed-bed ion exchanger at simultaneous removal of monadic ions of cesium and divalent ions of strontium from sewage in the constant electric field that increases the rate of external mass transfer. The calculations carried out show an increase in mass-transfer coefficient and volumetric mass-transfer coefficient for cesium by one third and for strontium by 2.2 times under electric field strength of 100 V/m. The increase in these factors leads to nine-fold increase in the basic cycle time. To ensure the set electric field strength, it is offered the scheme of ion-exchange column with disc-electrodes.
