Spectrophotometric/Spectrofluorimetric Determination of Rare Earth Mixtures by their Characteristic Absorption or Fluorescence of 4f Electron Transitions

Abstract

This review deals with the spectrophotometric and/or spectrofluorimetric determination of individual rare earth elements in rare earth mixtures by their characteristic absorption or fluorescence of 4f electron transitions, including conditions of maximal absorption or fluorescence, molar absorptivity, ranges of linearity, detection limits, interference, and application of these methods with 136 references cited.
