Determination of rare-earth elements in nitric acid solutions with high concentrations of uranium and macrocomponents

Spectral and matrix effects of uranium and other macrocomponents on the determination of rare-earth elements ( REE ) are studied. The experimental data are updated and verified using a fractional factorial experiment. A procedure is developed for the direct determination of REE in solutions with hig...

Zusammenfassung:Spectral and matrix effects of uranium and other macrocomponents on the determination of rare-earth elements ( REE ) are studied. The experimental data are updated and verified using a fractional factorial experiment. A procedure is developed for the direct determination of REE in solutions with high concentrations of uranium and fission products ( FP ) using inductively coupled plasma-atomic emission spectroscopy ( ICP-AES ).
