Title: Complications in complexation kinetics for lanthanides with DTPA using dye probe molecules in aqueous solution

Journal Article · · RSC Advances
DOI:https://doi.org/10.1039/C7RA04755J· OSTI ID:1376481

The complexation kinetics for the polyaminopolycarboxylic ligand DTPA to lanthanides in acidic aqueous solution were investigated using the dye ligand displacement technique and stopped-flow spectroscopy. Significant rate differences were obtained for different dye probes used, indicating that the kinetics of the dissociation of the dye molecule significantly impacts the overall measured kinetics when using this common methodology. The conditions of the solution also influenced the dye-lanthanide-DTPA interactions, which reconciled previously disparate data in the literature.
