The synergistic solvent extraction of 13 lanthanides with mixtures of 8-hydroxyquinoline (HQ) and the crown ethers (S) 18-crown-6 (18C6) or benzo-18-crown-6 (B18C6) in 1,2-dichloroethane has been studied. The composition of the extracted species has been determined as LnQ(3) center dot S. The values of the equilibrium constant and separation factor have been calculated. Here, the effect of the synergistic agent (18C6 or B18C6) on the extraction process is discussed.

The thermolysis of the 8-quinolinol chelates of yttrium, lanthanum, cerium(III), praseodymium, neodymium, samarium, and gadolinium were studied on the thermobalance. It was found that the thermolysis of the chelates proceeded in three stages: (1) a small loss in weight (about 1%) in the temperature range 250 to 300°; (2) the oxidation of the organic material in the temperature range 350 to 525°; (3)
