S. Mishra et V. Chakravortty, BINARY MIXTURE OF PC88A AND TOPO AS EXTRACTANT FOR THORIUM(IV) FROM AQUEOUS HNO3 AND H2SO4 MEDIA, Journal of radioanalytical and nuclear chemistry, 207(1), 1996, pp. 53-62
Synergism is observed in the extraction of thorium(IV) by the binary m
ixture of PC88A and TOPO in the range 0.1-2.5M HNO3 solution. The incr
ease in acidity decreases the synergistic effect. Antagonism is observ
ed when the extraction is carried out in H2SO4 medium.
