“…The pH of pollutant solution is a factor which influences the removal efficiency because of the predominant role on the charge characteristics through the protonation and deprotonation of oxygen-containing groups on the biochar or biochar composite surface [129]. The pH value also influences the degree of ionization of the adsorbate [130]. Wang et al reported that anion adsorption is favored at pH less than the point of zero charge (PZC) because the adsorbent surface is positively charged.…”

“…When we examined the studies carried out with LECA, heavy metal removal was generally observed. In some studies regarding dye removal (for examples, Bentahar et al, 2019;El Kassimi et al, 2020;El Kerdoudi et al, 2023) comparative studies on LECA and the raw clay from which it is produced have not been conducted.…”

“…This circumstance creates signi cant concerns and issues regarding the treatment of wastewater resulting from the paint industry (Lout et al, 2023). It is of great importance to develop effective methods for removing dyes from aqueous medium (El Kassimi et al, 2020). In recent years, many strategies have been developed for the removal of these pollutants (El Kerdoudi et al, 2023).…”

This study investigated the removal of methylene blue (MB) dye from aqueous solutions using raw clay (RC) and expanded clay ball (ECB) with different particle sizes ( = < 200 mesh, and > 200 mesh). A series of studies such as operating time (1 to 90 min), RC and ECB dose (0.1 to 4g/L), pH (2 to 10), mixing speed (60 to 180 rpm) and temperature (20 to 45°C) were additionally conducted through the use of a batch system in order to optimize the process. Additionally, this study investigated the concepts of adsorption kinetics, isotherms, and thermodynamics of MB. RC and ECB were characterized through distinct physical – chemical methods including scanning electron microscopy (SEM), energy dispersive x ray spectrometer (EDAX), Fourier transform infrared spectroscopy (FTIR). The structural changes in the surface morphology of ECB caused it to exhibit lower adsorption capacity than RC. The removal occurred rapidly in the first few minutes. RC (20 min.) reached equilibrium faster than ECB (30 min.). Under optimal conditions, removal efficiencies of > 200 mesh RC, =<200 mesh RC, > 200 mesh ECB, =<200 mesh ECB were obtained as 97.5%, 95.76%, 39.26%, 91.81%, respectively. The results show that the pseudo-second order (PSO), with R2 ranging from 0.69 to 1, and the Langmuir isotherm model, with a good fit for the MB removal for all combinations, are in agreement with the experimental data According to the study results, the process was carried out endothermic and physical.

“…The compound has a high dipole moment value (=0.1785 Debye, when calculated using the cc-pVDZ basis set) when compared to the values of other basis sets, which is much higher. A big dipole moment indicates that the molecule has a significant amount of electronic charge polarity, which is the basic cause of the chemical reaction [53,54]. 7, and Figure 3 with energy function, along with the reagent that was investigated.…”

The purpose of this study was to provide a theoretical evaluation of the benzene ring, and three methyl groups (CH3) that give the chemical its name (mesitylene, or C9H12) using quantum computation. The theoretical characteristics of the research were investigated using Gaussian software (DFT)/B3LYP employing 3-21G STO cc-pVDZ VDD basis sets. The mesitylene structures' shape was then optimized using this knowledge. The calculations for the electronic properties, including excitation energies, wavelengths, EHOMO and ELUMO energies, (DOS), Molecular Orbital Theory (MOT), electronic charge destruction, FT-IR, and the RAMAN spectrum, were carried out by DFT. The thermochemistry results, which include entropy (S), molar heat capacity (Cv), and thermal energy (E) complement the electronic properties. The STO/B3LYP base set has an excellent value for the BG energy, which is calculated to be 6.562 eV. This result agrees with previous research 6.22 eV.
