- Sorption processes of naphthalene and β-naphtole on layered double hydroxides (synthetic anionic clays)E. ButenkoLayered Double Hydroxides (LDHs) also called anionic clays due to their similar layered structure display a strong specific area which drives to interesting adsorption properties. These properties were highlighted in several

- Interaction of soluble salts with clay mineralsG.V. Kharitonova, A.S. Manucharov, N.I. Chernomorchenko, N.S. KonovalovaSoluble salts interact with clay minerals quite easily and significantly change the structural organization of their particles (Van Olphen, 1977).Knowing sorption mechanisms one can evaluate mobility and bioavailability of this or

- Synthesis, structure and acid properties of zr-pillared tagan montmorillonite.M.M. Malimbayeva, N.A. ZakarinaPillared clays compose one of the most widely studied family among the new groups of microporousmaterials which has shown catalytic activity in acid mediated reactions like isomerization. Modification by pillaring is

- The influence of dry grinding on structural and thermochemical properties of kaoliniteV.V. Krupskaya, L.V. Melchakova, M.F. Vigasina, L.P. Ogorodova, I.A. Kiseleva, M. ButochnikovThe natural kaolinite from Angren deposit (Uzbekistan) was investigated by X-ray powder diffraction, IR-spectroscopy, thermal analysis and thermochemical methods. The dry initial sample (I) was grinded on the air for 15

- Interparticle interactions in water dispersions of montmorillonite from tagansky depositM.M. Ignatova, B.V. Pokidko, I.A. TutorskyWater dispersions of purified bentonite particles were prepared using different amounts solid phase. Some changes in rheological properties were demonstrated between in 1-2% bentonite suspensions during rheological experiments (fig 1).
