Abstract

A compound having a diglycol amic acid frame, DODGAA, has been synthesized as a new "green" extradant for lanthanides. The new extractant is composed of carbon, hydrogen, oxygen, and nitrogen atoms and is therefore fully combustible, producing gases without solid waste and its solubility in water is found to be very low. These properties avoid production of industrial waste from the incineration of degraded extractants and the risk of aquatic environmental pollution. In its extraction ability for lanthanide ions and its ability for their mutual separation, DODGAA is much superior to carboxylic acid type extractants, such as Versatic 10, which is also completely combustible. The extraction and separation performance of DODGAA is comparable to that of the less "green" organophosphorus extractants, such as PC-88A and DEHPA, that are widely used in current industry.
