“…Possible health risks for humans could not be excluded and health status of children should be examined from health risk assessment perspective in rare earth mining areas (De Boer et al, 1996;Tong et al, 2004). High concentrations of REEs may cause significant damage to ecosystem (Barry and Meehan, 2000). Some studies also focused on the toxic effects of REEs to plants from occupational and environmental exposures and the longterm hazardous environment effects (Sax, 1984;Suzuki et al, 1992).…”

“…All these reagents were of laboratory grade, purchased from Aldrich (Germany) and Riedel de Haen (Switzerland). The stock solutions of lanthanum and europium cations were prepared by dissolving the required amount of the corresponding nitrate salts La(NO 3 ) 3 .6H 2 O, Eu(NO 3 ) 3 .6H 2 O, 99,99% grade, from Alpha Aesar (Germany) in deionized water. Feed solutions were made by diluting the stock solutions.…”

The solvent extraction of lanthanum(III) and europium(III) by aminooctyldimethylene diphosphonic acid from nitrate media was investigated. The extraction percent of lanthanum(III) and europium(III) was measured as a function of various parameters such as: volume ratio, shaking time, the concentration of aminooctyldimethylene diphosphonic acid, ionic strength and media pH. The metal concentration in the aqueous phase before and after extraction was determined spectrophotometrically by the Arsenazo III method. The extracted species and equilibrium extraction equations were determined by the slope analysis method. It was found that adding KNO 3 at a concentration of 0.1 M significantly enhances the extraction yield for lanthanum(III) and europium(III). Decreasing the media pH caused a gradual decrease of extraction yields. The obtained results showed that extraction of lanthanum(III) and europium(III) from nitrate media using aminooctyldimethylene diphosphonic acid in chloroform is quantitative under well-defined conditions.

“…Therefore, sorption via attractive electrostatic interactions is the most plausible mechanism for ampicillin retention by the C/Fe 3 O 4 surface. Considering the wide importance of rare-earth ions in current technological devices and the related questions in terms of their environmental impact [32], the removal of La 3+ by the composite microspheres was investigated. C/Fe 3 O 4 demonstrated no significant La 3+ adsorption capability whereas the maximum removal capacity of HAp towards this species was ca.…”

Novel hierarchically-organized magnetic microspheres have been successfully developed that consist of an aqueous hollow core, a magnetic porous Fe 3 O 4 -carbon layer and a well-define hydroxyapatite (HAp) shell. The hollow magnetic carbon microspheres were prepared by ultrasonic spray pyrolysis and coated with HAp using a biomimetic approach. The resulting powders exhibit micro-and meso-porosity. The removal capacity of the composite spheres towards an antibiotic (ampicilin), a rare-earth ion (La 3+ ) and two heavy metals (Hg 2+ and Pb 2+ ) has been studied and compared with that of the individual components. The dual organic-inorganic affinity of the magnetic HAp/carbon conjugates was demonstrated, with synergetic effects being evidenced for heavy metal removal enlightening their potentialities in wastewater treatment.
