Gravimetric Determinations

Development of a simple and rapid EDXRF method for quantification of ZrO2 and HfO2 in aqueous and organic process stream solutions generated from a zirconium extraction facility

“…Various techniques are available in the literature for the determination of zirconium covering a wide range of concentrations. They include gravimetry, 3 wavelength dispersive X-ray fluorescence (WDXRF) spectrometry, 4,5 total reflection X-ray fluorescence (TXRF), 6 spectrophotometry, 7,8 ICP-AES, 9 AAS 10 etc. Among the available techniques, gravimetry and spectrophotometry methods are cumbersome and time-consuming methods and, therefore, are not preferred choices for reporting the results of process stream solutions where they are to be reported rapidly for taking decisions on downstream processing and also monitoring the zirconium extraction process on a real-time basis.…”
