    Author: Zeng X, Guo J, Liu W.
    Journal: Huan Jing Ke Xue; 2001 Sep; 22(5):65-9. PubMed ID: 11769231.
    Abstract:
    Hydroxy-alumium montmorillonite may serve as potential adsorbents for organic pollutants from wastewater. It was synthesized by titrating Na-montmorillonite with hydroxy-aluminum solution (OH-/Al3+ molar ratio was 2.4). From powder XRD data, it was shown that the interlayer(d001) of montmorillonite was increased greatly from 12.58A to 18.63A. Seven modified montmorillonite samples, including hydroxy-aluminum montmorillonite, were used to remove the dye of weak deep blue GR from water. The results showed that hydroxy-alumium montmorillonite had very high adsorption ability, only 0.0200 g could treat 25 ml weak deep GR with 95% removal. The different adsorption mechanisms of weak deep blue GR on modified montmorillonite: surface adsorption, ion-exchanging and partion, were suggested.
