Des nanosphères poreuses de magnétite Fe3O4 (PMNs) sont synthétisées pour éliminer d'une solution aqueuse les colorants anioniques Acid Red 57 (AR57) et Remazol Red (RR) et sont utilisées comme adsorbant de haute performance. La caractérisation des PMNs a été réalisée à l'aide de différentes techniques, telles que la spectroscopie infrarouge à transformée de Fourier, l'aire de surface mesurée par Brunauer Emmett-Teller (BET), la forme sphérique a été déterminée par TEM et la modification de surface a été calculée par microscopie électronique (SEM). Des variables...

Porous magnetite Fe3O4 nanospheres (PMNs) are synthesized for removal from an aqueous solution of anionic dyes Acid Red 57 (AR57) and Remazol Red (RR) and are used as a high-performance adsorbent. Characterization of PMNs was carried out using various techniques, such as Fourier-transform infrared spectroscopy, the surface area measured by Brunauer Emmett-Teller (BET), Spherical-shaped was determined by TEM and surface modification was calculated using electron microscopy (SEM) scanning. Variables such as initial pH, the dosage of adsorbent, contact time, and temperature were analyzed to find...

Date seed activated carbon (DSAC) was created from date seed powder using a chemical activation procedure including potassium hydroxide (1:1 weight ratio) as the activating agent and temperatures ranging from 500 to 700 oC. Powder X-Ray diffraction was used to describe the activated carbon that resulted. XRD patterns revealed amorphous carbon structure, and scanning electron microscopy was used to examine the surface morphology of DSAC. Iodine adsorption properties of date seed-derived activated carbon was good, with an iodine number value of 798 mg/g, which is substantially greater than...

Poröse Magnetit Fe3O4-Nanokugeln (PMNs) werden zur Entfernung von anionischen Farbstoffen Acid Red 57 (AR57) und Remazol Red (RR) aus einer wässrigen Lösung synthetisiert und als Hochleistungsadsorptionsmittel eingesetzt. Die Charakterisierung der PMNs wurde mit verschiedenen Techniken durchgeführt, wie z.B. Fourier-Transform-Infrarotspektroskopie, die Oberfläche wurde mittels Brunauer-Emmett-Teller (BET) gemessen, die Kugelform wurde mittels TEM bestimmt und die Oberflächenmodifikation wurde mittels elektronenmikroskopischer (SEM) Abtastung berechnet. Variablen wie der anfängliche...

The structure of the ligand (HL) and its complexes were confirmed by elemental analyses, IR, 1H NMR, molar conductance, and thermal analysis data. Therefore, from the IR spectrum, it is concluded that HL binds to the metal as a monobasic bidentate ligand by coordinating via the nitrogen atom of the azo group (-N=N-) and the oxygen atom of the deprotonated phenolic OH group. The calf thymus DNA binding activity of the ligand (HL) and its metal complexes was studied by absorption spectra. Molecular docking and binding energy calculations of azo dye with the receptor of breast cancer...
