Iron Removal from Kaolins by Bacterial Leaching
Weathering of rocks generated large volumes of kaolin clays, quartz sands and micas, as well as other minerals, especially iron and titanium oxides. Kaolin is an economically important raw material often used in wide variety of ceramic applications, from high quality tableware and sanitaryware to electrical porcelain, tiles and glasses. There are some less common uses including glass fibre, whi...
متن کاملHydroxyl Deformation in Kaolins
-The hydroxyl deformation modes of kaolins have been studied by Fourier transform (FT) Raman spectroscopy. Kaolinites showed well-resolved bands at 959, 938 and 915 cm 1 and an additional band at 923 cm ~. For dickites, well-resolved bands were observed at 955, 936.5, 915 and 903 cm I. Halloysites showed less-resolved Raman bands at 950, 938, 923, 913 and 895 cm 1. The first 3 bands were assign...
متن کاملMossbauer Spectra of Soil Kaolins from South-western Australia
-Six well-characterized soil kaolins from widely separated sites in south-western Australia and four reference kaolins were studied by 57Fe M6ssbauer spectroscopy at room temperature after removal of non-structurally-bound iron with dithionite-citrate-bicarbonate solution. The soil kaolins and one of the reference kaolins were also studied at temperatures near 16 K. The soil kaolins were remark...
متن کاملPhase Transformations in Clays and Kaolins Produced by Thermal Treatment in Chlorine and Air Atmospheres
−A study of the phase transformations generated by chlorine during the calcination of clays and kaolins is presented. The original samples and residues of the thermal treatment carried out in air and chlorine atmospheres are analyzed at different calcination times and temperatures. Sample characterization was performed by X-ray diffraction (XRD), scanning electron microscopy (SEM) and Xray micr...
متن کاملPRODUCTION, RELEASE AND THERMAL CHARACTERIZATION OF CELLULOLYTIC ENZYME FROM CELLULOMONAS sp. STRAIN "0"
Cellulase production by a Cellulomonas sp., isolated in 1985 from forest humus soil along the border of the Caspian Sea in Iran, was investigated. This strain secreted endo-and exo-cellulases in the culture medium, but some of the enzymes produced remained cell membrane bound. Cell bound enzymes were released by various treatments. The highest amount of endo-glucanase (up to 95%) and exo-gl...
