Synthesis, characterization and sorption studies of a zirconium(iv) impregnated highly functionalized mesoporous activated carbons

Abstract

The present work focuses to develop a varied meso-microporous sorbent by using Zr(iv) as an impregnated metal. The modification develops the oxidative functionalities and porosity of the sorbent that enhances its efficiency for the removal of RB19.

Effect of Pyrolysis Temperature during Valorization of Date Stones on Physiochemical Properties of Activated Carbon and Its Catalytic Activity for the Oxidation of Cycloalkenes

“…Figure 1shows that all the diffractograms exhibit the typical activated carbon pattern with a strong peak at 25 • and a weak peak at around 45 • values of 2θ [20]. These peaks can be attributed to carbon planes of 002 and 101, and this is in conformity with the hexagonal structure of graphitic carbonaceous materials [10,20]. Notably, there are small yet important differences in the intensity of the major peak around 25 • .…”

“…Studies have also investigated various procedures for synthesizing these materials and their effects. The effects of chemical activation, physical activation, impregnation ratio, temperature, and activating agents have all been the subject of recent studies [7,9,10]. Detailed and varying analysis of the morphology and porosity of activated carbon synthesized from various biowaste sources has confirmed that the type of raw material and conditions of synthesis can greatly impact the key performance properties of activated carbon [7,11,12].…”

Augmentation of the coagulation activity of alum using a porous bio-flocculant for the remediation of trihalomethanes-generating hydrophobic natural organic matter

“…1 (a). The spectral range of 1,600-1,800 cm -1 corresponds to the C=O bond stretching and carbonyl group present in the protein and fatty acid structures [10,43,44]. The peak at 1,610.27 cm -1 shows the presence of aromatic C-C and C-H bonds, and the peak at 2,925.48 cm -1 shows the symmetric and asymmetric stretching of the C-H group present in fatty acid [45].…”

Recent advances on the removal of dyes from wastewater using various adsorbents: a critical review

“…These unique characteristics generally originate from their internal pore morphology, surface characteristics, porosity, pore volume, chemical structure, and the presence of functional groups of the source material, including its activation process. [102][103][104] The commercial activated 16 carbon and activated carbon synthesized from various waste materials are discussed in the subsequent section.…”
