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, HA)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. In this communication, we attempt to separate scandium from the lanthanidesand some other elements by the extraction with BPMDD under suitable conditions.
