Adsorption behavior of Rare-Earth ions on electrospun fibers functionalized with branched polyethyleneimine

The development of easily recoverable adsorbents containing abundant and accessible binding sites is essential for the efficient recovery of rare-earth ions from aqueous media. In this study, a branched polyethyleneimine-polyacrylonitrile (bPEI-PAN) fibrous adsorbent was fabricat...

Balancing thermal insulation and mechanical performance in aerogel insulating mortar through synergistic cement-HPMC regulation

This study develops a synergistically regulated aerogel insulating mortar (AIM) by integrating aerogel-modified expanded perlite, hollow glass microspheres, and HPMC. Response surface methodology (RSM) quantifies the coupled effects of cement content and HPMC dosage on dry densit...

Removal of Residual Ammonium from Weathered Crust Elution-Deposited Rare Earth Ore Tailings by Magnesium Chloride: Kinetics and Mass Transfer

After in situ leaching of weathered crust elution-deposited rare earth ore (WREO), large amounts of residual ammonium (RA) salts remain in the ore body and slowly release, causing persistent ammonia-nitrogen pollution in surrounding waters. This study proposes using magnesium chl...
