文摘
- •
Montmorillonite adsorbents were prepared with organic and/or inorganic pillars.
- •
Cr(VI) adsorption by adsorbents was pH-dependent with maximum removal at low pH.
- •
Adsorption equilibrium time was 2 h and followed pseudo-second-order kinetics model.
- •
The pseudo-second-order kinetics model indicated chemical adsorption of Cr(VI).
