| 摘 要： | Due to the ferro-philic and rock-philic geochemical properties, dispersion of resources as well as itscomplicated composition, the properties of scandium are similar to those of the lanthanide. Hence, its separa-tion from the lanthanides and iron is an important subject which has been studied extensively.1,10-bis(1'-phenyl-3'-methyl-5'-oxopyrazole-4'-yl)decane-1, 10-dione(BPMDD, H_2A)is a β-diketone chelating agent, and has a strong extracting power. The extraction of Sc with this chelating agenthas not been reported so far~(1]). In this communication, we attempt to separate scandium from the lanthanidesand some other elements by the extraction with BPMDD under suitable conditions.
