Аннотация:
Gel formation has been studied in the bulk of the organic phase and in the interphase of the Tb(OH)3 (Tb(NO3) 3)-bis(2-ethylhexyl) hydrogen phosphate-decane-water systems. In the Tb(OH)3-HDEHP-decane-water system, gel formation is observed over the bulk of the organic phase cHDEHP/cTb(OH)3≤ 1.8. A structured layer several tens of micrometers thick is formed when an aqueous Tb(NO 3)3 solution is in contact with an HDEHP solution in decane. The share of the structured layer in the interphase increases from 0 to about 90% as the terbium concentration increases. The structured layer that appears during the extraction of terbium by HDEHP in decane consists of both amorphous portions and portions dominated by acicular crystals. © Pleiades Publishing, Inc., 2006.
