X-ray fluorescence analysis of lanthanide mixtures: Ce, Pr, Nd, Sm, Eu, Gd. These mixtures were prepared from 0.1 M stock aqueous solutions of corresponding lanthanide nitrates in 0.01 M nitric acid. Lanthanide concentrations in mixtures were varied in a range from 10− 6 to 10− 3 mol/L. After dilution the pH of all solutions was adjusted to 2 by nitric acid. This concentration range was relevant to numerous practical analytical tasks, like quantification of lanthanides in monazite ores, analysis of spent nuclear fuel reprocessing media and other technological solutions. To design the mixtures we employed the approach based on a uniform distribution of samples in a concentration hyperspace.
