Recycling rare earth elements (REEs) contained in electronic waste is of utmost importance due to their ever-increasing use the high-tech sector. In this context, non-polluting techniques represents a real challenge for scientists. work, we demonstrated that clean and energy-efficient process, diffusion dialysis, has great potential recovery neodymium (Nd) praseodymium (Pr), Nd-Fe-B magnets end...

In this study, the adsorption behavior of an alginate biopolymer microspheres containing D2 EHPA/TOPO (DTMCs) toward samarium (III) and gadolinium (III) ions was examined under various conditions. Scanning electron microscope (SEM) and thermogravimetric analysis (TGA) techniques were used to characterize the structure of microspheres. The average size of the microspheres was estimated around 50...

A dispersive solid-phase microextraction (DSPME) sorbent consisting of poly(1,6-hexanediol diacrylate)-based polymer microspheres, with embedded graphene microparticles (poly(HDDA)/graphene), was synthesized by microfluidic emulsification/photopolymerization and characterized optical microscopy X-ray fluorescence spectrometry. This applied for simple, fast, sensitive vortex-assisted DSPME rare ...

Uranium is separated from the raffinate of Isfahan’s uranium conversion solvent extraction process by means of solvent coated magnetic nanoparticles. These particles were synthesized via chemical co-precipitation and were analyzed by XRD, TEM and TGA methods. The particles’ surface were modified with D2EHPA and analyzed with FT-IR method. The results revealed that 0.5 M nitric acid and 25% w/w ...
