Overview

Randomized trial investigates regeneration and adsorption of organic contaminants using pillared clay adsorbents, suggesting effective wastewater management solutions.

Key Points

  • The aim is to evaluate the regeneration performance of iron- and aluminum-pillar montmorillonite adsorbents for removing orange methyl from water.
  • Synthesis of Fe-Mt and Al-Mt adsorbents from Algerian bentonite using iron and aluminum hydroxyl polycations.
  • Characterization via x-ray, FTIR spectroscopy, SEM, and surface charge analysis.
  • Evaluation of adsorption behavior under varying pH, contact time, initial concentration, and adsorbent dose.
  • Optimal regeneration achieved with 0.001 M NaOH for 30 min, demonstrating high desorption efficiency.
  • Slight decreases in adsorption capacity observed over successive cycles; however, significant reusability retained.
  • Statistical physics models provided insights on the improved dye uptake following structural modifications.
