| Abstract: | Transport of uranyl ion across a
bulk chloroform membrane containing thenoyl trifluoro acetone (TTA) as carrier
has been studied. The pH of the feed solution was maintained at 4 to 5 while
0.1M nitric acid served as stripping agent in the receiving compartment of the
permeation cell. Various factors affecting the transport process have been
studied and the optimum experimental conditions have been established. The
optimum pH was adjusted to 5-5.5 while 0.1M HCl served as receiving solution.
Presence of EDTA as masking agent in the feed solution eliminated the
interference from Th(IV) and transition metal ions. The membrane system has
been applied to the recovery of uranium from synthetic seawater. A forty-fold
preconcentration of uranium with 96.46 recovery of the metal ion in a single
stage operation could be accomplished. |
