The goethite waste adsorbent (GWA) was characterized with scanning electron microscope (SEM), X-ray powder diffraction (XRD), and particle size distribution analysis. The adsorption of As(III) on GWA was studied as a function of contact time, pH, and coexisting anions. ...
The characteristics of β-CD/GPTMS/GO were detected by scanning electron microscopy (SEM), Fourier transform infrared, X-ray diffraction (XRD), thermogravimetric analysis (TG) and energy dispersive X-ray (EDX). ...
Characterization of the ternary composites was done using Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD) and thermogravimetric analysis (TGA). Kinetic models and adsorption isotherms were also studied. ...
In an attempt to control CaCO3 deposits in industrial recycling water systems, the performance of acrylic acid (AA)–allylpolyethoxy carboxylate (APEL) copolymer as an economical and environmentally friendly inhibitor have been investigated by static experiments, scanning electron microscopy (SEM), X-ray diffraction (XRD), and thermogravimetric analysis (TGA). ...
The used clay was characterized by X-ray diffraction (XRD) and X-ray fluorescence analysis. Aqueous solutions of heavy metals were prepared in the laboratory and filtered through the ceramic membranes. ...
Surface modification resulted in a lower Brunauer–Emmett–Teller (BET) surface area and pore size because of the collapse and blockage of pores, according to the X-ray diffraction (XRD) analysis, while the total number of surface oxygen acid groups increased, and this was supposed to contribute to the enhanced adsorption capacity of modified activated carbon. ...
The adsorbent (NGO) was characterized by X-ray diffraction (XRD) analysis and scanning electron microscopy analysis. Variables in the adsorption process were bed depths (5, 10 and 15 cm), flow rate (1, 2 and 4 mL/min), influent 4-chlorophenol concentrations (5, 10, 15, 20 and 30 mg/L) and influent solution pH (6–7). ...
The Fourier transform infrared spectroscopy (FTIR) and X-ray diffraction (XRD) analysis of this adsorbent were investigated. Response surface methodology was applied to evaluate the main effects and interactions among initial pH, initial Cr(VI) concentration, adsorbent dose and temperature. Analysis of variance depicted that resin dose and ...
Optimized (1:10) RGO-TiO2 nanocomposite was characterized by various techniques viz. X-ray diffraction (XRD), transmission electron microscopy (TEM), thermogravimetric analysis (TGA), Brunauer–Emmett–Teller surface area (BET), Raman and diffuse reflectance spectroscopy (DRS) technique confirming successful formation of nanocomposite. XRD results ...
The surface characteristics of the adsorbent were studied using Fourier transform infra-red (FTIR), scanning electron microscope, and X-ray diffraction (XRD) techniques. The presence of functional groups such as hydroxyl and carbonyl onto walnut green hull surface was proved by FTIR analysis. Also quartz, cellulose and hematite were detected in the ...
The various characterization techniques such as X-ray diffraction (XRD), field-emission scanning electron microscopy, N2 absorption–desorption and diffuse reflectance UV–visible spectrometry gave important information on the unusual structural features of the perovskite-related niobate nanosheets. XRD analysis of the exfoliated nanosheets showed a ...

The raw and water–washed fly ashes were selected for the pozzolanic solidification experiment to which mass ratios of the solution to ash (ml/g) were adjusted to be 3 and 10, whereas the solidification times were set from 7 to 28 days and from one to three months. From the XRD Rietveld analysis, a mineral assemblage of fly ash exhibited pozzolanic reactivity to ...
The nanocatalysts were characterised using XRD, FESEM, FTIR and BET analysis. The XRD patterns represented that by adding ZrO 2 to Ni-Co/Al 2 O 3 -MgO, the crystallinity declined and amorphous behaviour became intensified. ...
We report on the structural properties of porous anodic alumina (PAA) film produced by the anodisation technique under different annealing temperatures. X–ray diffraction (XRD) and photoluminescence (PL) measurements were performed. For the samples annealed in oxygen, decreases in the PL intensity and blueshift of the PL peak energy are observed with increasing annealing ...
Optical, compositional, morphological and structural studies were performed by UV-VIS-NIR spectrophotometry, X-ray photoelectron spectroscopy (XPS), scanning electron microscopy (SEM) and X-ray diffraction (XRD) studies. XPS studies revealed the formation of tungsten trioxide with oxygen deficiency. Analysis of the particle size (diameter) distribution of the ...
