Overview

This study shows increased adsorption of BTEX in water using HDTMA and TMPA-modified montmorillonite, suggesting effective remediation methods.

Key Points

  • Modified montmorillonite clay shows higher adsorption capacities for BTEX compounds, with Mt-HDTMA outperforming Mt-TMPA significantly.
  • Adsorption kinetics are best described by the pseudo-second-order model, indicating that chemisorption is the main mechanism in play.
  • Isotherm analysis suggests multilayer adsorption on heterogeneous surfaces using the Freundlich model for describing the process.
  • Density functional theory calculations support experimental results, showing stronger adsorption energies for HDTMA-modified clay.
