STUDY ON EXTRACTION PROPERTIES OF DRDECMP-TBP-KEROSENE Ⅰ.AVOIDANCE OF THE SECOND ORGANIC PHASE FORMATION IN EXTRACTION OF HNO_3 Gd

The formation and avoidance of a second organic phase during the extraction of HNO 3 and Gd with DRDECMP TBP kerosene have been studied.The influence of concentrations of DRDECMP, TBP in organic phase and nitric acid in aqueous phase and temperature on a second organic phase formation and loading capacity of Gd have also been studied. The recommended organic phase component for extraction flowsheet is 25%DRDECMP 45%TBP kerosene.
