Saline slag waste as an aluminum source for the synthesis of Zn–Al–Fe–Ti layered double-hydroxides as catalysts for the photodegradation of emerging contaminants
(Elsevier, 2020)
info:eu-repo/semantics/article,
In this work, aluminum extracted from saline slag waste is valorized to create a layered double-hydroxide series containing zinc and various proportions of aluminum/titanium. Materials were synthesized by the co-precipitation ...
Adsorption of rhodamine 6G and humic acids on composite bentonite-alginate in single and binary systems
(Springer, 2018)
info:eu-repo/semantics/article,
In this work, the preparation, characterization, and sorption of rhodamine 6G and humic acids on a composite sodium alginate-bentonite were investigated. Their structure and morphology were analyzed by several techniques, ...
Synthesis of high-surface-area C3N4 deposited on halloysite-derived silica nanotubes: enhanced visible light degradation of norfloxacin
(Elsevier, 2024)
Artículo / Artikulua,
Silica nanotubes, obtained from halloysite clay nanotubes that were calcined and acid-activated, were used as support for graphitic carbon nitride (g-C3N4) via a simple deposition method. They were chosen in order to avoid ...
Zn-Ti-Al layered double hydroxides synthesized from aluminum saline slag wastes as efficient drug adsorbents
(Elsevier, 2020)
info:eu-repo/semantics/article,
This work reports the synthesis of Zinc-Titanium-Aluminum (ZnTiAl) layered double hydroxides (LDH) with various proportions of Al[sbnd]Ti and a Zn/(Al[sbnd]Ti) molar ratio of 3:1 by the co-precipitation method. Two series, ...
Optimizing the removal of nitrate by adsorption onto activated carbon using response surface methodology based on the central composite design
(Taylor & Francis, 2020)
info:eu-repo/semantics/article,
This study sheds light on the adsorption process for the removal of nitrate ions from synthetic aqueous solutions. This contaminant pose a potential risk to the environment and can cause health effects including cancers ...
Catalytic photodegradation of organic compounds using TiO2/pillared clays synthesized using a nonconventional aluminum source
(Elsevier, 2022)
Artículo / Artikulua,
This study evaluates the photocatalytic degradation of 2,6-dichlorophenol (2,6-DCP), triclosan (TCS) and bisphenol A (BPA) by ultraviolet (UV) and visible (VIS) light in the presence of TiO2/catalysts synthesized by wet ...
Effect of the surface properties of Me2+/Al layered double hydroxides synthesized from aluminum saline slag wastes on the adsorption removal of drugs
(ElsevierInternational Zeolite Association, 2020)
info:eu-repo/semantics/article,
This work presents the synthesis of Me2+ (Co, Mg, Ni and Zn)/Al layered double hydroxides (LDH) with a 3:1 M ratio by the co-precipitation method. Structural characterization and comparison of the series has been achieved ...
A nonconventional aluminum source in the production of alumina-pillared clays for the removal of organic pollutants by adsorption
(Elsevier, 2021)
Artículo / Artikulua,
This study is the first to propose the use of aluminum saline slag as aluminum source in the synthesis of alumina pillared clays (Al-PILC). Aluminum was extracted from this waste using both alkaline and acid solutions and ...
Inorganic–organic hybrids based on sepiolite as efficient adsorbents of caffeine and glyphosate pollutants
(Elsevier, 2020)
Artículo / Artikulua,
Sepiolite clay mineral was functionalized with (3-chloropropyl)triethoxysilane (ClPTES) or 3-[tri(ethoxy/methoxy)silyl] propylurea (TEMSPU) alkoxides and tested as adsorbent for herbicide glyphosate and also of caffeine, ...
Effect of high pressure on the reducibility and dispersion of the active phase of Fischer-Tropsch catalysts
(MDPI, 2019)
info:eu-repo/semantics/article,
The effect of high pressure on the reducibility and dispersion of oxides of Co and Fe supported on -Al2O3, SiO2, and TiO2 has been studied. The catalysts, having a nominal metal content of 10 wt.%, were prepared by incipient ...
