Extraction of lanthanide ions by 2-methyl-8-quinolinol

Technical Report ·
OSTI ID:5691247

The equilibrium extraction behavior of a series of tervalent lanthanides (La, Pr, Eu, Ho, and Yb) with 2-methyl-8-quinolinol (HL) in chloroform has been studied. Although the sterically hindered extractant does not form neutral LnL/sub 3/ complexes, ion pair complexes of intermediate chelates with either perchlorate or thiocyanate ions are extractable. The extraction constants of such species are smaller than those of other 8-quinolinols and closer together because the adverse steric influence of the 2-methyl group is greater on the heavier lanthanide ions. 12 refs., 3 figs., 1 tab.
