Adsorption recovery of Ag(I) and Au(III) from an electronics industry wastewater on a clay mineral composite
(University of Science and Technology BeijingSpringer, 2019)
info:eu-repo/semantics/article,
The aim of this work is to investigate the ability of an adsorbent of a clay mineral composite to remove and recover gold and silver ions from wastewater. The composite was prepared by mixing phosphogypsum (PG), obtained ...
Zeolite synthesis from aluminum saline slag waste
(Elsevier, 2020)
info:eu-repo/semantics/article,
This work describes the synthetic procedures developed to obtain zeolite X (NaX), zeolite A (LTA) and sodalite (SOD) using aluminum saline slag waste (AlSSW) as aluminum source in a two-step hydrothermal method involving ...
M(II)-Al-Fe layered double hydroxides synthesized from aluminum saline slag wastes and catalytic performance on cyclooctene oxidation
(Elsevier, 2022)
info:eu-repo/semantics/article,
Aluminum was extracted from saline slags via an alkaline method and employed in the synthesis of Layered Double Hydroxides (LDH) with various M2+ cations (Co, Mg, Ni and Zn), while Al and Fe were the M3+ cations, using the ...
White and red Brazilian Sao Simao's kaolinite-TiO2 nanocomposites as catalysts for toluene photodegradation from aqueous solutions
(MDPI, 2019)
info:eu-repo/semantics/article,
The presence of volatile organic compounds in groundwater is a major concern when it is used as a drinking water source because many of these compounds can adversely affect human health. This work reports on the preparation ...
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 ...
Progress in the synthesis and applications of hexaaluminate-based catalysts
(Taylor & Francis, 2020)
info:eu-repo/semantics/article,
The development of materials that can exhibit thermal resistance at very high temperatures, thus allowing them to be applied as catalysts and thermal insulators, amongst other possible uses, is a research subject of great ...
Use of response surface methodology to optimize triclosan adsorption on alumina pillared clays in a fixed-bed column for applications in solid-phase extraction
(Elsevier, 2023)
Artículo / Artikulua,
Fixed-bed column studies are generally conducted to consider possible applications in water-purification processes. In this work, three synthetic alumina pillared interlayered clays (Al-PILC) were analyzed in fixed-bed
column ...
Understanding the formation of Al13 and Al30 polycations to the development of microporous materials based on Al13-and Al30-PILC montmorillonites: a review
(Elsevier, 2021)
Artículo / Artikulua,
Hydrolysis of aluminum cations (Al3+), the third most abundant metal in the Earth’s crust, is considered relevant
in many academic fields, including materials science and chemical engineering. AlIII -polycations and ...
Synthesis of zeolite a from metakaolin and its application in the adsorption of cationic dyes
(MDPI, 2018)
info:eu-repo/semantics/article,
The present work reports the synthesis of zeolites from two metakaolins, one derived from the white kaolin and the other derived from the red kaolin, found in a deposit in the city of São Simão (Brazil). The metakaolins ...
Multifunctional heterogeneous catalysts: Tetrakis (pentafluorophenyl)porphinato]iron(III) immobilized on amine-functionalized Diatomaceous Earth for catalytic and adsorption applications
(Elsevier, 2023)
Artículo / Artikulua,
The use of Diatomaceous Earth (DE) as a promising support of a synthetic metalloporphyrin is reported, trying to
heterogenize metalloporphyrin catalysts to mimicking enzyme site isolation and improving reaction selectivity.
New ...
