ABSTRACT:
The kinetics of reduction of tris(1, 10 orthophenanthroline ) iron(III) by [N -(2-hydroxyethyl)-ethylene-diamine-N’, N’, N’ -triacetato] uranium (IV), symbolized as [U(IV) HEDTA]1+, has been investigated in aqueous medium at 30 0.5oC . Measurements were recorded under pseudo first order conditions. The rate of electron transfer reaction between these reactants was measured by varying pH and ionic strength, between 2.5-3.0 and 0.01-0.05 M respectively. It was found that pH directly influenced the k1 and values were found to be 111.8, 193.7, 344.7 478.93 mol-1 dm 3 s-1 at pH 3.2, 3.0, 2.8, 2.5 respectively. The value of k’ was evaluated as 6.35X106 mol-1 dm 3 s-1.
Abbreviations: EDTA=Ethylene-diamine-N,N ,N-tetra acetic acid, HEDTA=[N-(2-hydroxyethyl)-]ethylene-diamine-N’, N’, N’-triacetattic acid.
