18 p, 1.8 MB Solubility and thermodynamic properties of carbonate-bearing hydrotalcite-pyroaurite solid solutions with a 3:1 Mg/(Al+Fe) mole ratio / Rozov, K. B. (University of Bern. Rock-Water Interaction Group) ; Berner, U. (Paul Scherrer Institut. Laboratory for Waste Management) ; Kulik, D. A. (Paul Scherrer Institut. Laboratory for Waste Management) ; Diamond, L. W. (University of Bern. Rock-Water Interaction Group)
The naturally occurring layered double hydroxides (LDH, or anionic clays) are of particular interest in environmental geochemistry because of their ability to retain hazardous cations and especially anions. [...]

7 p, 442.4 KB The dispersive effect of sodium silicate on kaolinite particles in process water : Implications for iron-ore processing / Ma, Mark (CSIRO Process Science and Engineering)
Kaolinite is a common gangue mineral in iron ore and sodium silicate has been used widely as a dispersant of silicate gangue minerals including kaolinite in various iron-ore flotation methods over a wide range of pH. [...]

10 p, 1.1 MB Clean-up of wastes from the textile industry using anionic clays / Flores, Jorge (Universidad Autónoma Metropolitana (Mèxic)) ; Lima, Enrique (Universidad Nacional Autónoma de México. Instituto de Investigaciones en Materiales) ; Maubert, Marisela (Universidad Autónoma Metropolitana (Mèxic)) ; Aduna, Enrique (Universidad Autónoma Metropolitana (Mèxic)) ; Rivera, Jose Luis (Universidad Nacional Autónoma de México. Instituto de Investigaciones en Materiales)
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. [...]

9 p, 731.1 KB A study of the removal of copper ions from aqueous solution using Clinoptilolite from Serbia / Stojakovic, Djordje (University of Belgrade. Innovation Centre of the Faculty of Technology and Metallurgy) ; Milenkovic, Jelena (University of Belgrade. Faculty of Technology and Metallurgy) ; Daneu, Nina (Jozef Stefan Institute) ; Rajic, Nevenka (University of Belgrade. Faculty of Technology and Metallurgy)
Toxic metal contamination of waste waters can be mitigated by metal adsorption to clay and zeolitic minerals, but in developing countries such environmental remediation can be cost prohibitive if these minerals are not readily available. [...]

13 p, 1.5 MB Upper cretaceous clayey levels from western Portugal (Aveiro and Taveiro regions) : Clay mineral and trace-element distribution / Marques, Rosa (Universidade de Aveiro. GeoBioTec Research Centre) ; Dias, Maria Isabel (Universidade de Aveiro. GeoBioTec Research Centre) ; Prudêncio, M. Isabel (Universidade de Aveiro. GeoBioTec Research Centre) ; Rocha, Fernando (Universidade de Aveiro. GeoBioTec Research Centre)
Clay-rich deposits of Upper Cretaceous levels in the Taveiro (Reveles and S. Pedro) and Aveiro (Bustos) regions of west-central Portugal are economically and environmentally important, but detailed chemical and mineralogical characterization is lacking. [...]

8 p, 817.4 KB Effects of gel parameters on the synthesis and characteristics of W-type zeolite nanoparticles / Maghsoodloorad, Hojjatollah (Iran University of Science and Technology. Research Centre for Membrane Separation Processes) ; Mirfendereski, Seyed Mojtaba (Iran University of Science and Technology. Research Centre for Membrane Separation Processes) ; Mohammadi, Toraj (Iran University of Science and Technology. Research Centre for Membrane Separation Processes) ; Pak, Afshin (Iran University of Science and Technology. Research Centre for Membrane Separation Processes)
The objectives of this study were to investigate the effects of chemical parameters on the characterizationof W-type zeolite crystals and their intergrowths with other types of zeolites. The crystal size and purity ofW-type zeolites are affected significantly by the gel composition with respect to the molar ratios of SiO /Al O (aluminosilicate module, α),H O/K O (alkainity, β), and water content (H O/SiO , γ).
