Abstract

The extraction of complexes of silver, mercury, cadmium, cobalt, zinc, scandium and some rare earth elements (Ln) into benzene solutions of 1,1-disubstituted 3-diphenoxythiophosphorylthioureas (HA) containing alkyl and aryl substituents was examined using the radiotracer technique. The complexes AgA(HA), HgA<sub>2</sub>, CdA<sub>2</sub> and LnA<sub>3</sub> are extracted into the organic phase, and the extraction increases in order Co, Zn, Cd ≈ Ln &lt;&lt; Hg &lt; Ag. The extraction constants were calculated. During the extraction process using medium acidic aqueous phases (1 M HNO<sub>3</sub>), the reagents decompose into the corresponding amines and (PhO)<sub>2</sub>P(S)NCS.
