“…Determination of rare earths from various types of environmental samples is particularly important because it can serve to establish a sample fingerprint, and thus, the results could be used in determining the origin of the concerned sample and to identify sources of pollution [15,16]. Mass spectrometry with inductively coupled plasma offers the possibility to measure the rare earths with an excellent accuracy, which cannot be achieved by any another method [17,18].…”

A study was carried out to determine the accumulation of trace metals in water, sediments, and soil from several locations in the Transylvania region (Romania), using the inductively coupled plasma mass spectrometry (ICP-MS) technique. A significant number of metals (range of several μgL −1 ) were identified, the toxic metal concentrations in mostly of the investigated waters being within the permissible limits. A seasonal variation in the metal content was also observed. Comparison of the metal concentrations to samples of sediment, soil, and vegetation coming from the surrounding areas of the same water reservoir revealed a higher accumulation of rare and toxic metals in sediments than in soil and vegetation.

“…Moreover, solid phase extraction (SPE), adsorption, dry digestion, ion exchange chromatography and biosorption are available in addition to magnetic separation and electrostatic separation. The supporting practices which used in the physical ore extraction are usually such as activated charcoal, silica gel, activated alumina, zeolites, membranes and synthetic polymeric resins (Nasab et al, 2011;Ashour et al, 2016;Zhang et al, 2016b;Amaral et al, 2017;Hidayah, and Abidin, 2017;Quinn et al, 2017;Rivera et al, 2018;Cao et al, 2019;Ponou et al, 2019;Gupta et al, 2019;Chen et al, 2019;Léniz-Pizarro et al, 2021). Very strong acids carry out in the solvent extraction during the extraction process of REEs and then these chemicals leach out into the environment and be transported through water bodies and cause the acidification of aquatic environments.…”

Due to the transition from traditional energy sources to clean energy in recent years, it is stated that there will be a continuous increase in the need for REEs worldwide in the coming years owing to their especial physical and chemical properties. The principal sources of REEs are the minerals bastnazite, monazite, and xenotime, etc.. Rare earths have peculiar, unique properties and become essential in many high-tech applications. Therefore, the REEs is used for applications such as improvement of industrial. It is worth highlighting that the separation of rare earth can be both complex and challenging owing to similar properties which are shared to produce high quality and better quantity of REEs. In industrial production, complex ores containing rare earth elements are concentrated by physical ore beneficiation processes. For this, the processes proposed in this work possesses aguide on green chemistry, solvent extraction, membran filtration, adsorption of recovering REEs through stepwise extraction and enrichment technique. This review, attempts to provide notable information on the separation and purification efforts to date for the recovery of REEs.

In this paper, magnetic mesoporous carbon composites were prepared by calcination of the mixture of magnesium citrate and Fe 3 O 4 @SiO 2 in an inert atmosphere. A high content of Fe 3 O 4 @SiO 2 and MgO was in situ embedded in a carbon matrix. After removing the MgO template by diluted acid, the resulting material (Fe 3 O 4 @SiO 2 @mC) was subjected to further H 2 O 2 oxidation treatment. The formed oxygen-containing functional groups on the products provided plenty of active sites for the adsorption of analytes of interest. The obtained composites (Fe 3 O 4 @SiO 2 @mC-H 2 O 2 ) exhibited a mesoporous structure with a high specific surface area of 731 m 2 g –1 . The adsorption capacities of Fe 3 O 4 @SiO 2 @mC-H 2 O 2 for Cu(II) and Pb(II) were calculated to be 86.5 and 156 mg g –1 , respectively. Under optimal conditions, the adsorption isotherm of Cu(II) and Pb(II) onto Fe 3 O 4 @SiO 2 @mC-H 2 O 2 fitted the Langmuir model and the adsorption kinetic was well-correlated with the pseudo-second-order model. Besides, Fe 3 O 4 @SiO 2 @mC-H 2 O 2 exhibited fast removal dynamics (within less than 1 min) for Cu(II) and Pb(II), demonstrating great application potential in wastewater treatment.
