Effect of particle size on copper removal by layered double hydroxides
(Elsevier Science Sa, 2016-06-03)
Layered double hydroxides are increasingly studied as heavy metal scavengers but the effect of particle size in their removal behavior has not been explored yet. Here, these aspects were studied in three solids with similar ...
Ciprofloxacin-intercalated layered double hydroxide-in-hybrid films as composite dressings for controlled antimicrobial topical delivery
(Elsevier Science, 2020-06)
Films based on biopolymers and loaded with antimicrobial agents are convenient pharmaceutical dosage forms for topical application. Inorganic carriers loaded with these agents lead to composite materials, which combined ...
Pros and cons of coating layered double hydroxide nanoparticles with polyacrylate
(Elsevier Science, 2019-05)
Preventing the aggregation of layered double hydroxide nanoparticles (LDH-NP) and producing additional functionality are two important objectives for their applications as drug nanocarriers, among others. Adsorption of ...
Copper, lead and cadmium removal by Ca Al layered double hydroxides
(Elsevier Science, 2014-01)
Layered double hydroxides are increasingly studied as heavy metal scavengers due to their acid/base buffering capacity that leads to hydroxide precipitation. Their intercalation with ligands such as edta also provides ...
Potencial de hidróxidos duplos lamelares de Zn-Al e Mg-Fe para adsorção de 2-nitrofenol
(Universidade Federal de Santa MariaBrasilEngenharia QuímicaUFSMPrograma de Pós-Graduação em Engenharia QuímicaCentro de Tecnologia, 2020-02-28)
Two Zn-Al and Mg-Fe layered double hydroxides (LDH) were synthesized by coprecipitation method in order to increase the adsorption potential of 2-nitrophenol (2-NP). Both adsorbents were characterized by the techniques of ...

Adsorption of Acid Yellow 42 dye on calcined layered double hydroxide: Effect of time, concentration, pH and temperature
(2017-05-01)
The adsorption of textile dyes onto Layered Double Hydroxides (LDH) and their thermally decomposed products is a promising strategy for the treatment of contaminated effluents - combining high removal efficiency with ...
Fenton-like degradation of methylene blue using Mg/Fe and MnMg/Fe layered double hydroxides as reusable catalysts
(2020-03-15)
In this work, the Layered Double Hydroxide (LDH) containing magnesium (Mg) and iron (Fe) was modified with Mn to investigate the effect of the addition from the structural and catalytic point of view. These materials were ...
Mg-Fe layered double hydroxide modified montmorillonite as hydrophilic nanofiller in polysulfone- polyvinylpyrrolidone blend ultrafiltration membranes : separation of oil-water mixture
(2020-07)
Montomorillonite (Mt) and Mg[sbnd]Fe layered double hydroxide modified Montmorillonite (LDH-Mt) were used as nanofillers in polysulfone - Polyvinylpyrrolidone (PSF-PVP) blend ultrafiltration membranes. The nanocomposite ...
Glycerol steam reforming over layered double hydroxide-supported Pt catalysts
(Elsevier Science Sa, 2015-03)
Layered double hydroxides containing Mg and Al (Mg/Al ratios of 3 and 5) were used as support for Pt-based catalysts for glycerol steam reforming. Additionally, catalysts supported on the parent MgAl mixed oxides were also ...
