“…The low adsorption capacity of Mg-ZSM-5 is ascribed to the weak affinity of the alkaline earth metal cations for CO2, which is consistent with the behavior related to alkaline earth metal cation-exchanged zeolite beta [31]. The Zn 2+ cation of the transition metal group has little cation radius and is favorably situated at the site of IV leads to an important increment in adsorption performance, which was revealed by the same manner for the ZnCHA [32][33][34].…”

In this paper, a synthesized zeolite (ZSM-5) is used as an adsorbent to analyze the adsorption phenomenon of carbon dioxide. This investigation, based on the statistical physics treatment, applied the multilayer model with saturation to understand the CO2 adsorption on four samples, namely M-ZSM-5 (M = Na+, Mg2+, Zn2+, La3+), at various temperatures T = 0 °C, 30 °C and 60 °C. The modeling results indicated that CO2 adsorption occurred via a non-parallel orientation on the ZSM-5 surface. The CO2 adsorption capacities varied from 26.14 to 28.65 cm3/g for Na-ZSM-5, from 25.82 to 27.97 cm3/g for Mg-ZSM-5, from 54.82 to 68.63 cm3/g for La-ZSM-5 and from 56.53 to 74.72 cm3/g for Zn-ZSM-5. Thus, Zn-ZSM-5 exhibits the highest adsorption amount. The analysis of the adsorption energies shows that the adsorption of CO2 on ZSM-5 zeolite is a physisorption phenomenon that could be controlled thanks to the energy parameters obtained via the numerical findings using the multilayer statistical model. Finally, the distribution of site energy was determined to confirm the physical character of the interactions between adsorbate/adsorbent and the heterogeneity of the zeolite surface.

“…The advent and development of plasma technology have also made it possible to improve the surfaces properties of biomass. Non-thermal plasma is a source of highly oxidizing (°OH, NO°, H2O) and acidifying (HNO2, HNO3) agents [25,26], which can react with the surface of the biomass and bring some modifications in their characteristics. Thus, several works [26][27][28], have reported that non-thermal modification of carbonbased plasma with O2 as feed gas in dry atmosphere improved the adsorption capacity of adsorbent whereas the use of N2 or Ar under the same conditions reduced the specific surface area and pore volume.…”

In addition, the wood industries have produced billions of tons of sawdust and shavings that are usually destroyed by combustion or used as fuel for cooking, with consequences on the greenhouse effect due to the large amount of CO2 released.…”

The Removal of an anionic Reactive Blue 2 (RB2) dye in an aqueous solution was successfully achieved using a plasma-modified agricultural biomaterial waste. Sawdust from Moabi (Baillonellatoxisperma) and Sapelli (Entandrophragmacylindricum) was modified using non-thermal gliding arc plasma. The natural raw materials and plasma treated were characterized by Infrared Spectroscopy (FTIR), Thermogravimetric Analysis (TGA), Scanning Electron Microscopy (SEM), XRD, Chemical analysis by Fluorescence, Sorption Analyser, and Zetametry. Experimental parameters such as initial pH, contact time, adsorbent dose, initial RB2 concentration, and temperature were optimized. The results showed that the removal of Reactive Blue 2 dye was favorable at acidic pH conditions with the maximum capacity going from 172,85 to 200,91 mg.g-1 to 98,19 and 149,02 mg.g-1 respectively for raw and plasma-treated Sapeli and Moabi. The Avrami fractional-order kinetic provided the best fit to the experiments data and the thermodynamic adsorption data of untreated (SSB and SMB) and plasma-treated (SSM and SMM) sawdust followed an exothermic process. This work demonstrated that non-thermal plasma modified wood sawdust can be a good alternative absorbent for the removal of dye pollutants from an aqueous solution.
