Description

PMR spectroscopy was used to study the complexation of rare earth ions with EDTA. Some analytical capabilities of PMR spectroscopy in the analysis of mixtures of rare earth elements were examined. An express method was developed of selective determination of Gd(3) in the presence of La,Lu,Y on the basis of EDTA signal broadening. The limit of detection is detection is 10-7 mol/l, the relative standard deviation 0.022-0.24
