“…Over the years, it can be seen that the interest of scientists in the determination of rare earth metals by various methods is growing. So far, the instrumental techniques used for the detection and quantification of lanthanides include spectroscopic techniques such as graphite furnace atomic absorption spectrometry (GFAAS) [13], inductively coupled plasma optical emission spectrometry (ICP-OES) [14][15][16] and X-ray fluorescence spectroscopy (XRF) [17,18]; spectrometric technique, i.e., inductively coupled plasma mass spectroscopy (ICP-MS) [19][20][21] or spectrophotometry [22]; and other techniques such as neutron activation analysis (NAA) [23] and high-performance liquid chromatography (HPLC) [24]. NAA is a very sensitive approach, but the chief downsides of this method are the need for a source of neutrons as well as the irradiated samples becoming radioactive.…”

This paper presents an overview of approaches proposed in the scientific literature for the voltammetric determination of rare earth elements (mainly cerium and europium individually, as well as various lanthanides simultaneously) in manifold kinds of samples. The work is divided into chapters describing the most important aspects affecting the sensitivity of the proposed methods: the technique adopted (AdSV, ASV, CSV), complexing agents used, the kind of working electrode (mercury-based, noble metal or carbon electrodes) and the most popular electrode modifiers (e.g., metal film, carbon nanotubes, molecularly imprinted polymers). Analytical parameters of the procedures presented in the paper are collected in tables. The subsequent chapters are devoted to a detailed discussion of potential inorganic and organic interfering factors. The possibilities of simultaneous determination of several lanthanides in one sample and the influence of other lanthanides on the determined rare earth element were also discussed. Finally, the applications of the voltammetric procedures to the determination of rare earth metals in real samples with miscellaneous matrix is described. All analytical results were tabulated in order to compare the analytical suitability of the proposed procedures.

A new sensitive, accurate, and non-extractive spectrophotometric method was developed for the rapid determination of Uranium in pure form and Uranium ore using roxarsone. The procedure was based on the complex formation between Uranium (VI) and roxarsone. This showed maximum absorption at λmax 395 nm with a linear relationship in the concentration range from (20-100 µg mLˉ¹) with a molar absorptivity 9.57×103(1mol-1 cm-1). Inductively Coupled Plasma mass spectroscopy (ICP-MS) was used in the study of the interferences caused by some metallic ions, which were effectively masked by tartaric acid and diethylenetriaminepenta-acetic acid (DTPA). The method holds its accuracy and precision well when applied to the determination of the studied Uranium in its pure form and Uranium ore.
