| dc.description.abstract | N-phenylcinnamohydroxamic acid (PORA) has been found to form a convenient extraction system for uRnadium (V) in presence of p-chlorophenol and also in SON media. PORA reacts with vanadium (V) to give a 1:2 complex (having a broad peak around 54-0 nm with 6200 litres/mole/cm). In the presence of an adduct forming substance (p-chlorophenol) synergic extraction of the metal and marked absorbance enhancement into chloroform have been observed on the basis of formation and hyper and bathochromic shift of the hydrophobic species formed. Similar effect is seen in the mixed ligand complex system. The complexes are found to have the composition 1:2:1 or 1:2:2 (V: POUA: PhOR) depending upon the nmount of p-chlorollhenol available during the reaction; and 1:2;2 (V: PORA: bOn) mixed | en_US |
