  • Solvent Extraction Behavior of Inorganic Ions in the Alkylamines-hydrochloric Acid Systems Amberlite LA-1 and tri-iso-octylamine

抄録

The extraction behavior of more than 60 chemical elements in the systems of 10% Amberlite LA-1 xylene solution vs. hydrochloric acid and 5% tri-iso-octylamine xylene solution vs. hydrochloric acid is presented and discussed, the acidity being varied from 1 to 12M. The distribution ratio, Kd, of the particular nuclide was determined by the use of radioactive tracer. Although the shapes of the acid dependence curves for each element resemble each other in the two systems, yet the Kd values in the TIOA system are generally higher than those obtained in Amberlite LA-1. The same regularity is to be noticed for the relationship between the Kd values of the elements at a definite acidity and their respective atomic number, Z, in the two systems examined. By comparison with the TBP-HCl, or the anion exchange resin-HCl systems, it is to be found that amines give acid and Z dependence curves quite analogous to those of the two former systems. The higher Kd values for scandium and heavier rare earth elements in the TBP-HCl system are, however, a rare exception.
