Summary

Rare earth elements are classed as critical raw materials, and recovering them from the water streams of processed electronic waste is attractive because adsorption is simple, cheap and effective. This study embeds nanometric cerium oxide particles into electrospun fibres to act as the adsorbent, giving the nanoparticles a supporting structure that can be handled, deployed and retrieved - the practical obstacle that usually stands between a good adsorbent powder and a usable recovery system.
