The solvent extraction behavior of about sixty chemical elements was surveyed in the system of 10% (v/v) Primene JM-T xylene solution vs. hydrochloric acid, the acidity being varied 112 N. The distribution ratio, Kd, of a particular nuclide was determined by the use of radioisotope tracer.
The Kd values of this Primene JM-T-HCl system were usually below one. Iron, gallium, antimony and protactinium were extractable above 6 N-hydrochloric acid, while gold.alone could be extracted all over the hydrochloric acidity tested.
The present results were compared with those for secondary or tertiary amine extraction.
