Synthesis, Characterization, and Modification of Alumina Nanoparticles for Cationic Dye Removal

open access: yesMaterials, 2019
In the present study, alumina nanoparticles (nano-alumina) which were successfully fabricated by solvothermal method, were characterized by X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FT-IR), Transmission Electron Microscopy (TEM ...

Determination of the influence of organic and inorganic impurity on physico-chemical properties of detergent zeolite type 4A

open access: yesZaštita Materijala, 2016
This paper shows the synthesis of detergent zeolite type 4A, on the precise conditions of crystallization with time of 4 hours at 85°C. Zeolites without impurities were synthesized with clean raw material and also zeolites with the addition of organic ...

Prediction of Red Mud Bound-Soda Losses in Bayer Process Using Neural Networks [PDF]

open access: yesIranian Journal of Chemical Engineering, 2016
In the Bayer process, the reaction of silica in bauxite with caustic soda causes the loss of great amount of NaOH. In this research, the bound-soda losses in Bayer process solid residue (red mud) are predicted using intelligent techniques.

Alumina: discriminative analysis using 3D correlation of solid-state NMR parameters.

open access: yesChemical Society Reviews, 2019
Synthetic transition aluminas (χ, κ, θ, γ, δ, η, ρ) exhibit unique adsorptive and catalytic properties leading to numerous practical applications. Generated by thermal transformation of aluminium (oxy)hydroxides, structural differences between them arise

A Novel Synthesis Route of Mesoporous γ-Alumina from Polyoxohydroxide Aluminum

open access: yes, 2018
Mesoporous gamma-aluminas (γ-Al2O3) were synthesized starting from an unusual precursor of polyoxohydroxide aluminum (POHA). This precursor was obtained from aluminum oxidation in alkaline water-ethanol solvent in the presence of d-glucose that induces ...

Examination of the influence of treatments and mineral composition on the point of zero charge of red mud

open access: yesZaštita Materijala, 2018
Red mud represents tailings which remains after the processing of bauxite into alumina by Bayer's proceedings. All the elements are present in the red mud are found in the form of different minerals.

Extraction of Alumina from Nawan Kaolin by Acid Leaching

open access: yesOriental Journal of Chemistry, 2019
This paper investigated the production of alumina from Nawan kaolin by acid leaching with sulfuric and hydrochloric acids. Kaolin was calcined at 850°C and was leached with 6 M acid at 90°C, 5M NaOH followed by HCl solutions were added to the leaching ...
