Article Synopsis
  • Rare Earth Elements (REE) found in acid mine drainage (AMD) pose environmental risks, and their capture through Alkaline Passive Treatment Systems (PTS) is the focus of this study.
  • Batch experiments were conducted to simulate PTS conditions, using pH adjustments of AMD samples to identify how REE are trapped in secondary mineral phases, particularly between pH 4-6.
  • Findings indicate that most REE are associated with aluminum and iron phases, while some light REE are integrated into gypsum through co-precipitation at lower pH, suggesting effective removal strategies in deeper PTS layers.

Dissolved Organic Matter (DOM) can affect the mobility of radionuclides in pore water of clay-rich geological formations, such as those intended to be used for nuclear waste disposal. The present work studies the adsorption and transport properties of a polycarboxylic acid, polymaleic acid (PMA, Mw=1.9kDa), on Callovo-Oxfordian argillite samples (COx).
