Description

The cascade experiments of complexing re-extraction experiments for separating Np from U by coordination stripping neptunium with DTPA have been carried out. The results showed that the separation factors were more than 10 in all selected experimental conditions. the recovery of U was different for different conditions of acidity of TBP supplement extraction liquid and number of stages. The recovery of U was 98.3% in the condition of three supplement extraction stages and 0.6 mol/L HNO3 in TBP supplement extraction liquid
