Determining the selectivity of a tetra-phosphorylated biomimetic peptide towards uranium in the presence of competing cations through the simultaneous coupling of HILIC to ESI–MS and ICP-MS

Atomic spectrometry update: review of advances in elemental speciation

“…These results are in agreement with those previously obtained by other spectroscopic techniques, which were used to validate the method. In the second paper 143 the developed molecular and inorganic MS detection system was used to determine the effect of competing divalent metals including, Ca, Cu and Zn, on the binding of the uranyl ion UO 2 2+ to a synthetically prepared model tetra-phosphorylated peptide. Because of the isobaric interferences on the main Ca isotope Sr was used as a substitute.…”
