Adsorption of disperse dyes from wastewater onto Ni-Zn LHS (layered hydroxide salts) and Mg-Al LDH (layered double hydroxides) has been compared in this study. Effects of initial pH solution, contact time and initial dye concentration were investigated. T... see more

The formation process of LDHs (layered double hydroxides) coating on magnesium alloy by the CO2 pressurization method was studied. The micro-structure was observed by OM, SEM and GAXRD. The weighted gain curve, apparent activation energy, and CO2 solubili... see more

Synthesis of p-hydroxybenzoic acid (PHBA)-intercalated Mg/Al-LDH and PHBA-immobilized Mg/Al-LDH have been conducted. PHBA-intercalated Mg/Al-LDH hybrid was synthesized by co-assembly process of Mg/Al-LDH nanosheets and PHBA anions. PHBA-immobilized Mg/Al-... see more

Layered double hydroxide (LDH) Cu/Al and Cu/Cr had been used as adsorbent of malachite green (MG) in aqueous solution. The properties of Cu/Al and Cu/Cr LDHs were analyzed by X-ray diffraction, surface area analysis (BET) and FTIR spectroscopy. Adsorption... see more

Layered double hydroxide (LDH) of Zn/Al and citrate-Zn/Al was prepared and used as an adsorbent of Congo red from aqueous solution. LDH was characterized by X-ray, FTIR, and BET analysis. Adsorption of Congo red was studied through kinetic, isotherm, and ... see more

The study proposed a new formulation to the sustained delivery of mefenamate anions intercalated into Mg–Al layered double hydroxide (LDH) for oral administration. Different experimental conditions were evaluated to incorporate the mefenamic acid (MEF) an... see more

A Dietilnitrosamina (DEN), uma substância reconhecidamente hepatotóxica e carcinogênica, foi utilizada na indução da necrose hepática centrolobular em ratos isogênicos Lewis divididos em 5 grupos de 5 animais. O objetivo deste estudo foi avaliar o efeito ... see more

This research introduces a completely new environmental benign synthesis route for obtaining two kinds of inter-mediate and high temperature CO2 sorbents, Mg-Al layered double hydroxide (LDH) and Li4SiO4, from vermiculite. The mineral vermiculite was leac... see more
