Synthesis of pollucite and analcime zeolites by recovering aluminum from a saline slag
(Elsevier, 2021)
info:eu-repo/semantics/article,
This work describes a valorization procedure for one of the most important wastes generated during aluminum recycling, namely, saline slag. This procedure was divided in two steps: a) recovery of aluminum or its compounds ...
Progress in the removal of pharmaceutical compounds from aqueous solution using layered double hydroxides as adsorbents: a review
(Elsevier, 2020)
info:eu-repo/semantics/article,
Emerging contaminants and, among them, pharmaceutical compounds, have a significant impact on water ecosystems. Layered Double Hydroxides (LDH), being easy to synthesize and cheap materials, have recently gained attention ...
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 ...
Synthesis strategies of alumina from aluminum saline slags
(Elsevier, 2023)
Artículo / Artikulua,
Aluminum saline slags is a waste of the metallurgical industry that presents serious environmental problems
since it needs very extensive areas for its disposal, the toxicity it causes in the atmosphere and groundwater, ...
A comparative study of acid and alkaline aluminum extraction valorization procedure for aluminum saline slags
(Elsevier, 2022)
Artículo / Artikulua,
A management process for saline slags, one of the wastes from Secondary Aluminum Production, is proposed. The process begins with a grinding step, followed by washing with water, which removed the fluxing salts but provoking ...
Preparation of Ca2Al1–mFem(OH)6Cl 2H2O-doped hydrocalumites and application of their derived mixed oxides in the photodegradation of ibuprofen
(MDPI, 2022)
Artículo / Artikulua,
Aluminum from saline slags generated during the recycling of this metal, extracted under
reflux conditions with aqueous NaOH, was used in the synthesis of hydrocalumite-type solids with
the formula Ca2Al1–mFem(OH)6Cl ...
Titania-triethanolamine-kaolinite nanocomposites as adsorbents and photocatalysts of herbicides
(Elsevier, 2021)
info:eu-repo/semantics/article,
Kaolinite-titania adsorbents/photocatalysts were prepared by functionalizing a kaolinite with titanium(IV) triethanolaminate isopropoxide by the sol–gel route. These materials were characterized by various techniques and ...
Preparation of Al/Fe-PILC clay catalysts from concentrated precursors: enhanced hydrolysis of pillaring metals and intercalation
(Royal Society of Chemistry, 2020)
info:eu-repo/semantics/article,
The modification of bentonite with Al-Fe species from different concentrated precursors at both stages: (i) the preparation of the (Al/Fe)-mixed pillaring solution and (ii) intercalation itself, was studied at lab scale. ...
Effect of the preparation method and metal content on the synthesis of metal modified titanium oxide used for the removal of salicylic acid under UV light
(Taylor & Francis, 2018)
info:eu-repo/semantics/article,
Titanium dioxide modified with Ag and Fe was synthesized using two preparation methods, characterized and applied to the photocatalytic degradation of salicylic acid in aqueous solution. The modified TiO2 samples were ...
Effective degradation of methylene blue in aqueous solution using Pd-supported Cu-doped Ti-pillared montmorillonite catalyst
(Elsevier, 2019)
info:eu-repo/semantics/article,
The effluents from the textile, paper and food industries contain organic dyes that are strongly colored and reveal harmful effect on living systems. In order to reduce water pollution, the degradation of dye into non toxic ...
