Comments on: The Application of Visible Absorption Spectroscopy to the Analysis of Uranium in Aqueous Solutions

Abstract

Comments on the application of visible absorption spectroscopy to the analysis of uranium in aqueous solutions are presented. This manuscript is lacking in update of literature survey on the analysis of uranium in aqueous solutions in concentrates. There is nothing new innovation contained in this publication. An update on a comparative analytical performance of their proposed application of visible absorption spectroscopy to the analysis of uranium in aqueous solutions in concentrates with those other reported analytical methods will give a better understanding of the developed analytical protocol. Application of Differential technique in spectrophotometry (DTspectrophotometry) /laser-/LED-induced fluorimetry (DT-LIF/DT-LED-LIF)/ICP-OES (DT-ICP-OES) has inherent high metrological quality and warrants its introduction as a relative reference measurement procedure.
