  • Clays and Clay Minerals, Vol. 54, No. 2, 153-164, 2006. 
    Peltier, Edward; Allada, Ramakumar; Navrotsky, Alexandra; Sparks, Donald L. (The Clay Minerals SocietyThe Clay Minerals Society, 2006)
    The formation of mixed-metal-Al layered double hydroxide (LDH) phases similar to hydrotalcite has been identified as a significant mechanism for immobilization of trace metals in some environmental systems. These precipitate ...
  • Clays and Clay Minerals, Vol. 54, No. 3, 382-389, 2006. 
    Kayano, Mihoko; Ogawa, Makoto (The Clay Minerals SocietyThe Clay Minerals Society, 2006)
    Cobalt (II) and Al (III) layered double hydroxides were precipitated from homogeneous solutions using urea hydrolysis under hydrothermal conditions. The particle sizes were controlled successfully by changing the reaction ...

    Abstract—The sorption of nitrate ions on calcined hydrotalcite-type compounds at 550ºC (HT550), 650ºC (HT650), and 850ºC (HT850) from pure water solution at 25ºC has been studied. The influence of the temperature was also ...
  • Clays and Clay Minerals, Vol. 56, No. 6, 633–644, 2008. 
    Ayala-luis, Karina Barbara; Koch, Christian Bender; Hansen, Hans Christian Bruun (The Clay Minerals SocietyThe Clay Minerals Society, 2008)
    Mixed FeIIFeIII hydroxides, commonly referred to as ‘green rusts’ (GRs), are important reactive phases in both man-made and natural geochemical systems. Determinations of the standard Gibbs energy of formation of GRs are ...
  • Clays and Clay Minerals, Vol. 57, No. 1, 82–92, 2009. 
    Prasanna, S. V.; Radha, A. V.; Kamath, P. V.; Kannan, S. (The Clay Minerals Society, 2009)
    Because of the anisotropy in bonding, layered hydroxides crystallize with extensive structural disorder due to the incorporation of stacking faults. In contrast, the loss of crystallinity in Br-ion intercalated layered ...
  • Clays and Clay Minerals, Vol. 57, No. 3, 330–337, 2009. 
    Hansen, Birte; Curtius, Hilde; Odoj, Reinhard (The Clay Minerals Society, 2009)
    Leaching experiments with metallic uranium-aluminum research-reactor fuel elements in repository-relevant MgCl2-rich salt brine (brine 2) were performed. A Mg-Al layered double hydroxide (LDH) with chloride as the interlayer ...
  • Clays and Clay Minerals, Vol. 57, No. 4, 425–432, 2009. 
    Kovanda, Frantisek; Masatova, Petra; Novotna, Petra; Jiratova, Kveta (The Clay Minerals Society, 2009)
    Layered double hydroxides (LDHs) are often used as precursors for mixed-oxide catalysts and the deposition of a LDH layer on supporting materials would be advantageous because of better utilization of active components. ...
  • Clays and Clay Minerals, Vol. 59, No. 3, 240–249, 2011. 
    Flores, Jorge; Lima, Enrique; Maubert, Marisela; Aduna, Enrique; Rivera, Jose Luis (The Clay Minerals Society, 2011)
    Toxic dyes must be removed from waste water coming from the textile and paint industries. Adsorption is one possible method of removing dyes under ‘soft’ conditions, without the generation of secondary hazardous materials. ...
  • Clays and Clay Minerals, Vol. 59, No. 5, 438–445, 2011. 
    Wu, Pingxiao; Zhang, Qian; Dai, Yaping; Zhu, Nengwu; Li, Ping; Wu, Jinhua; Dang, Zhi (The Clay Minerals Society, 2011)
    Among the many techniques used to remove toxic dyes from the environment, layered double hydroxides (LDH) are considered to be especially environmentally friendly, but, this quality may be altered by variations in the ...
