Abstract
This paper introduces the study of elution test in the separation process of zirconium and hafnium with D296 resin in the ion exchange fixed bed.The temperature of the adsorption and elution tests was between 2 and 5 degrees Celsius.Elution tests was carried out in a saturated adsorption ion exchange column,an ion exchange column with exchange region,and an ion exchange column with exchange region and no adsorption region.The results showed that the status of the ion exchange column and the acidity of the eluting agent had a significant effect on the separation effect.When the ion exchange column had exchange region,with the any acidity of sulphuric acid elution,hafnium would be eluted first,but the high acidity of eluent was more favorable for the separation of zirconium and hafnium.When the ion exchange column was saturated adsorption state,with low acidity and high acidity of eluent,zirconium and hafnium could not get effective separation.Experiments proved that, the single fixed bed has low separation efficiency of zirconium and hafnium.In order to achieve separation of zirconium and hafnium,need to design the continuous moving bed separation.关键词
