“…A calibration curve was prepared by preparing DBT solutions of different concentrations (10–100 ppm). A UV/visible spectrophotometer (Shimadzu UV–160A Vis Spectrophotometer) was utilized to determine the absorbance of the prepared solutions at the specified wavelength (313 nm) 27,28 . Amount of the S‐containing compound per unit mass of adsorbent, q e (mg S/g), was determined using the following equation:

q_{e} = \frac{((), C_{0} - q_{e}) V}{W},

where C 0 and C e are the initial and equilibrium concentrations (ppm) of solute in the bulk phase, respectively; V is the volume of the solution; and W is the mass of the AC used (g).…”

The present study concentrates on the preparation of activated carbon (AC) from a low‐cost precursor, namely, polyethylene terephthalate waste, as a potential alternative adsorbent to commercially activated carbon for desulfurization of model gasoline at ambient temperature. Polyethylene terephthalate was carbonized at 450°C, and the produced char was steam activated at 750°C for 90 min to prepare the AC. The morphology, crystallinity, and surface functional groups of as‐synthesized adsorbent were examined by scanning electron microscopy, X‐ray diffraction, and Fourier transform infrared spectroscopy, respectively. The so‐synthesized AC was employed in the adsorptive desulfurization of dibenzothiophene (DBT) from model gasoline. The effect of the initial concentration of DBT, AC dose, temperature, and contact time on the removal efficiency of DBT was investigated. The maximum desulfurization level (97.10%) was performed at 40°C using 0.30 g of the AC for 60 min. The Langmuir model best demonstrated the adsorption results with an adsorption capacity of 49.56 mg/g. The pseudo‐second‐order model best described the adsorption kinetics of DBT by the so‐synthesized AC. The obtained consequences exhibited that AC with high desulfurization capability could be synthesized from polyethylene terephthalate waste.

“…All the samples have strong band at ∼3,430 cm −1 , which corresponds to characteristic bands of (-OH) [21]. The band around 1,730 cm −1 for GO related of the carboxylic acid Group (COO − ) [22], and the band at ∼1,620 cm −1 for GO assigned to (C=C) skeletal stretching. In addition, the band of ∼1,070 cm −1 for GO corresponds to the (C-O) vibration of various oxygen-containing group.…”

2015): Removal of Pb(II) ion from aqueous solution by graphene oxide and functionalized graphene oxide-thiol: effect of cysteamine concentration on the bonding constant, Desalination and Water Treatment, A B S T R A C TEfficient adsorbent graphene oxide (GO) and its derivative, i.e., thiol-functionalized graphene oxide (GO-SH), was used for the removal of noxious Pb(II) ion from the aqueous phase. Different amounts, i.e., 60, 80, and 100 mg of cysteamine, were used as functionalizing agent to functionalize the GO with thiol group; hence, three different nanocomposites, i.e., GO-SH 1 , GO-SH 2 , and GO-SH 3 were prepared from the different amount of the cysteamine. The developed nanocomposites were characterized using various analytical techniques such as Fourier transform infrared spectroscopy, scanning electron microscopy, and X-ray diffraction analysis. The whole removal and adsorption process was well illustrated and investigated. The impact of influential factors including initial concentration, pH, contact time, temperature, and concentrations cysteamine on the adsorption properties of Pb(II) from aqueous solution was well elucidated and optimized. The obtained equilibrium results were inserted in various adsorption isotherm models such as Langmuir (liner types I, II, III, and IV), Freundlich, Temkin, Helsey, and Dubinin-Radushkevich isotherms, it was found that the Langmuir (type I) model demonstrated was well fitted and in good agreement with the maximum adsorption of Pb(II) ion from aqueous solution. Thermodynamic functions, such as ΔG˚, ΔH˚, and ΔSẘ ere calculated and it reveals that the adsorption of Pb(II) ion on all the surfaces was spontaneous and endothermic in nature.

“…Hydrodesulfurization (HDS) work on the elimination of non-aromatic organosulphur compounds and thiophene at high pressure, high temperature, and hydrogen environment; however, it is challenging to eliminate aromatic organosulfur compounds. Therefore, the main drawbacks of Hydrodesulfurization are the high operations cost and lower octane number due to olefins saturation [2].…”

In this study, HKUST-1 prepared under solvothermal conditions and tested in desulphurization of model gasoline. The prepared HKUST-1 samples were characterized using surface area and pore volume analysis ( BET), powder X-ray diffraction( XRD), and Fourier transforms infrared spectroscopy (FTIR). The prepared HKUST-1 was used for desulphurization of model gasoline (thiophene with iso-octane), and the influence of the thiophene concentration, HKUST-1 dose, temperature, and contact time. The experimental results revealed that the sulfur content in model fuel was reduced from 1500 to 148.2 ppm (90.12% removal efficiency) for 4 hours contact time at 30 o C. In addition, an isotherm adsorption and kinetics study were performed for a batch process to understand the system equilibrium( i.e., the best fitting Langmuir isotherm or Freundlich isotherm). The kinetics study proved that the contained sulfur removal was best fitted by Pseudo-Second-Order Kinetics. Regeneration results show that the HKUST-1 has a reversible nature as an adsorbent. Therefore, HKUST-1 might be used as a promising adsorbent for removing thiophene compounds from gasoline.
