Unveiling the Zirconium and Hafnium Speciation in Fluoride‐Nitric Acid Solutions by Paper Spray Ionization Mass Spectrometry Combined with DFT Calculations

Paper spray ionization mass spectrometry (PSI‐MS) was used to detect a variety of species of hafnium and zirconium present in an aqueous acid solution containing NO3− and F− anions. This solution mimetics the acid waters used in separation/extraction processes. Hence, the information provided by PSI...
