“…In addition, separation of REE from the mixture of elements is necessary for a precise analysis [26]. Besides, classical spectrophotometric techniques are only suitable for determination of the total amount of REEs [38,39] due to their low absorption coefficient. According to Table 3, provided LODs are mostly in the range of µg mL -1 which are comparable with our obtained LOD.…”

Since lanthanides are inner transitional elements with their 4f and 5d energy levels closed, they possess narrow electronic absorption peaks, which are little affected by their chemical environment. In this research, a thermal lens microscope (TLM) that utilizing diode lasers as pump and probe beams was constructed for selective determination of Sm (III) without any pre-concentration and separation procedure. The calibration plot has a linear behavior over the 0.5-500 µgmL-1 range and a limit of detection (LOD) of 0.08 µg mL-1. The relative standard deviation (RSD) is smaller than 5%. This method can be potentially applicable to environmental studies.

“…Furthermore, it is widely used commercially in modern industrial fields to produce laser materials (Sharma et al, 2014). Analysis of its presence in samples is often carried out using spectrometric methods, such as visible light spectrophotometry, which involves the formation of a complex compound between the Eu 3+ ion and methylene blue (Bhattacharya et al, 2000). Another method is the application of atomic absorption spectrometry to determine europium hydroxide by coprecipitation technique (Soylak & Gokhan, 2006).…”

There is often a drawback during the determination of Eu in aqueous solvents using the voltammetric method. The current signal from water can reduce that of the element, which causes difficulty while separating the Eu signal from other rare earth elements (REE). Therefore, this study used acetonitrile as a solvent due to its high electrical conductivity and wide potential range. The optimum conditions for the determination of Eu in acetonitrile using the Box-Behnken design include 74.56 seconds deposition time, 0.125 V amplitude modulation, and -2.0 V potential deposition. The platinum electrode's performance showed a recovery value of 98.91% and accuracy and precision (in %RSD) of 96.67% and 1.11%, respectively. Furthermore, detection and quantitation limits of 0.6 mg/L and 5.1 mg/L were recorded from the analysis. It concluded that the differential pulse voltammetry method was applied to determine the presence of Eu in acetonitrile.
