Spectrophotometric determination of uranium(VI) using a synergic mixture of ethyl acetoacetate and pyridine
Description
A method is proposed for the extractive spectrophotometric determination of uranium(VI) using the synergic combination of ethyl acetoacetate (EAA) and pyridine (Py) as extractants. The optimum conditions have been evaluated by varying pH and ethyl acetoacetate and pyridine concentration. The nature of the extracted species has been determined by lg D-lg C plots and the extracted species was found to be UO2(EAA)2 x Py. The method has been applied for the separation and determination of uranium(VI) from synthetic mixtures. (author). 4 refs., 2 figs. 1 tab
