Adsorption of oxalate on gibbsite

Hydrometallurgy, 1986
Abstract The adsorption of oxalate ion on gibbsite was measured using a radiotracer. For oxalate concentrations of 2 to 18 mol/m 3 , Na 2 O of 0.1 to 0.125 g/cm 3 and Al 2 O 3 /Na 2 O of 0.21 to 0.32 by weight, the adsorption appears to about 0.02 μmol/m 2 , or less than 0.01 monolayer.

Atomic force microscopy of gibbsite

Applied Surface Science, 1998
Atomic force microscopy has been used to image the surface structure of a range of gibbsite (Al(OH)3) crystals. A variety of microtopographies has been imaged on the (001) plane, and sub-nanometer detail has been observed on flat areas that is commensurate with the known bulk structure of the solid.

Gibbsite scaling on polymer surfaces

Proceedings of the Institution of Mechanical Engineers, Part L: Journal of Materials: Design and Applications, 2012
Gibbsite scale build up was studied over a range of polymer surfaces in real Bayer process conditions. For all samples there was an initial slow rate of scale growth and there was evidence that this growth proceeded along scratches on the polymer surfaces.

Tailoring Mono-, Bi-, and Trimodal Molar Mass Distributions and All-Hydrocarbon Composites by Ethylene Polymerization on Bis(imino)pyridine Chromium(III) Supported on Ultrathin Gibbsite Single Crystal Nanoplatelets

Macromolecules, 2019
Multimodal molar mass distributions (MWD) of high-density polyethylene (HDPE) were tailored either by reactor cascade technology using a chain transfer agent or by multisite polymerization catalysis combining different single-site catalysts on the same ...

Novel eco-friendly method for preparation of mesoporous alumina from the product of rapid thermal treatment of gibbsite

Superlattices and Microstructures, 2018
Novel eco-friendly method for preparation of mesoporous alumina from the product of rapid thermal treatment of gibbsite (CTA product) without “reprecipitation” stage is described.

Thermodynamic assessment of Hg(II)–gibbsite interactions

Journal of Colloid and Interface Science, 2006
As discrete particles and/or as surface coatings on other minerals in natural systems, aluminum hydroxides are efficient sinks for Hg(II). The Hg(II) adsorption on gibbsite was determined as a function of temperature (T), pH, and the type of background electrolytes, i.e., NaNO(3), NaClO(4), and NaCl.

The adsorption of nortriptyline on montmorillonite, kaolinite and gibbsite

Applied Clay Science, 2018
Nortriptyline (NT) is a tricyclic antidepressant in common use in many countries. Its presence in drinking water indicates that current wastewater treatment practices fail to remove it effectively from effluents with consequent adverse effects on aquatic

Neptunium(V) sorption onto gibbsite

Radiochimica Acta, 2009
The sorption behavior of neptunium(V) on gibbsite (γ-Al(OH) 3 ) was studied by batch experiments in the presence/absence of ambient CO 2 as a function of solid-to-liquid ratio, pH, ionic strength, and Np(V) concentration. The sorption of 8 × 10 -6 M Np(V) at ionic strength of 0.1 M NaClO 4 was proportional to the solid-to-liquid ratio of gibbsite ...

Gibbsite‐Kaolinite Equilibria

Soil Science Society of America Journal, 1967
Abstract In order to help determine if the equilibria reached by soil mineral mixtures is that predicted on the basis of single minerals, two kaolinite samples were equilibrated individually and also with gibbsite of known stability. One set of samples was equilibrated from undersaturation, the other from supersaturation. Samples were

Halloysite and Gibbsite Formation in Hawaii

Clays and clay minerals (National Conference on Clays and Clay Minerals), 1960
AbstractDesilication and removal of bases from the basalitic rocks of the Hawaiian Islands produces large amounts of halloysite and gibbsite, together with variable quantities of allophane and nontronite, iron and titanium oxides, and amorphous mineral and gel material.The nature and relative abundance of intermediate and end products of weathering ...
