| Abstract: | The spectral characteristics of 4f electron transitions for some rare earth complexes formed with l-phenyl-3-methyl-4-benzoylpyrazolone-5 in the presence of triton X-100 are studied. A phtometric method is suggested to determine directly Nd and Er in mixed rare earths. It has been used to determine Nd and Er in two synthetic samples and a rare earth material, satisfactory results are obtained. |
