“…The adsorption process was conducted in batch mode using a Julabo SW23 shaker for sample shaking at a constant rotation speed (200 rpm). The adsorption performance of the obtained materials developed in the removal process of Mo(VI) anions from aqueous solutions was studied taking into account the influence of the Mo(VI) initial concentrations (15-200 mg/L), stirring time (5-240 min), and temperature (20,35, and 50 • C). For all the adsorption studies, the solid:liquid ratio between the adsorbent and Mo(VI)-containing aqueous solutions was 0.025 g in 25 mL (i.e., solid:liquid ratio (S:L) = 1 g/L).…”

“…From the multitude of Me 2+ /Me 3+ LDH types, much focus has been directed toward the Mg 2+ /Fe 3+ pair. A literature search revealed that Mg/Fe-LDH has been used for phosphate removal from aqueous solutions [9][10][11]; as adsorbent materials of various heavy metals, such as Cr, As, Pb, Zn, Cu, Se, Sb, and so forth [12][13][14][15][16]; for treatment of aqueous solutions contaminated with different reactive dyes [17][18][19]; or as a catalyst [20][21][22]. Presently, there is a focus on obtaining cheaper adsorbent materials that still retain properties similar to those obtained from pure chemicals.…”

The paper presents a new method of layered double hydroxide (LDH) synthesis starting from secondary sources, namely acidic residual solutions. The iron content of the acidic solution resulting from the pickling step of the hot-dip galvanizing process make it suitable to be used as an iron precursor in LDH synthesis. Here, Mg4Fe–LDH synthesized through the newly proposed method presented structural and morphological characteristics similar to the properties of layered double hydroxides synthesized from analytical-grade reagents. Moreover, the as-synthesized LDH and its calcined product presented efficient adsorption properties in the removal process of Mo(VI) from aqueous solutions. The adsorption studies are discussed from the equilibrium, kinetic, and thermodynamic points of view. The proposed novel technologies present both economic and environmental protection benefits.

“…According to the electromagnetic wave propagation theory, nanostructured materials with multiple interfaces show great potential as microwave absorbers due to their effective interfacial polarization and associated relaxation loss via surface scattering effects [ 6 , 8 , 9 ]. In recent years, plenty of special microstructure materials have been developed extensively and their performance in microwave absorption is generally superior [ 10 ].…”

Microwave-absorbing materials have attracted increased research interest in recent years because of their core roles in the fields of electromagnetic (EM) pollution precaution and information security. In this paper, microwave-absorbing material NiFe-layered double hydroxide (NiFe-LDH) was synthesized by a simple co-precipitation method and calcined for the fabrication of NiFe-mixed metal oxide (NiFe-MMO). The phase structure and micromorphology of the NiFe-LDH and NiFe-MMO were analyzed, and their microwave-absorbing properties were investigated with a vector network analyzer in 2–18 GHz. Both NiFe-LDH and NiFe-MMO possessed abundant interfaces and a low dielectric constant, which were beneficial to electromagnetic wave absorption, owing to the synergistic effect of multi-relaxation and impedance matching. The optimum reflection loss (RL) of NiFe-LDH and NiFe-MMO was −58.8 dB and −64.4 dB, respectively, with the thickness of 4.0 mm in the C band. This work demonstrates that LDH-based materials have a potential application in electromagnetic wave absorption.
