“…In addition, the reaction rate constant for the sonophotocatalytic system was 0.66, and it was 0.3 and 0.25 1/min for photocatalytic and sonocatalytic systems, respectively; as seen, the rate of DZN degradation by the sonophotocatalytic system is more than double that of other systems. In a study conducted by Al-Musawi et al for degrading acid blue 113 dye, the results showed that the sonophotocatalytic rate was approximately three to four times higher than that of photocatalytic and sonocatalytic systems [28].…”

“…Sonolysis has come to the fore in recent years, in which ultrasound radiation is adopted because of the absence of chemical involvement as a chemical reaction as well as its safety in use [26,27]. During the sonophotocatalytic process, which is a combination of photocatalysis and sonocatalytic processes, it is possible to generate large numbers of • OH radicals via ultrasound acoustic cavitation [28]. In addition, the catalytic regions are constantly regenerated by the cavitation process, which means the removal of byproducts and the effects of microcurrent and turbulence.…”

In this work, a hematite/porous graphite carbon-nitride (α-Fe2O3/g-C3N4) catalyst was synthesized through the doping of hematite loaded onto porous graphite carbon-nitride using a heat treatment process. Then, the ability of catalyst was evaluated to degrade diazinon (DZN) for the first time, mainly via the sonophotocatalytic process. Among the samples, the greatest DZN degradation was observed in the sonophotocatalytic system, which separated 100% of DZN from the aqueous solution after 50 min, while the removal percentages for the sonocatalytic, photocatalytic, and adsorption systems were 72.9, 89.1, and 58.1%, respectively. The results of scavengers showed that both sulfate and hydroxyl radicals (•OH) participated in removing DZN, although positive holes and negative •OH played a major role. Moreover, the removal efficiencies of the target pollutant using the sonophotocatalytic process were higher than those using the photocatalytic, sonocatalytic, and adsorption processes. The reaction profile followed pseudo-first-order kinetics, and the reaction rate coefficient for the sonophotocatalytic system was 2.2 times higher than that of the photocatalytic system and 2.64 times higher than that of the sonocatalytic system. The energy consumption of the sonophotocatalytic system after 60 min was 11.6 kWh/m3, while it was 31.1 kWh/m3 for the photocatalytic system. A DZN removal percentage of 100% was obtained after 50 min under the following conditions: UV intensity of 36 watts, ultrasound frequency of 36 kHz, DZN concentration of 50 mg/L at pH 5, and α-Fe2O3/g-C3N4 dosage of 0.4 g/L. The catalyst reusability was examined with only a 9.9% reduction in efficiency after eight consecutive cycles. The chemical oxygen demand (COD) and total organic compound (TOC) removal percentages were 95.6% and 88.6%, respectively, and the five-day biochemical oxygen demand (BOD5)/COD ratio was 0.16 at the beginning of the degradation process and 0.69 at the end of the process. In addition, toxicological experiments showed that degradation of DZN by the sonophotocatalytic process exhibited low toxicity. All results confirmed that the sonophotocatalytic process using α-Fe2O3/g-C3N4 was a highly efficient process for DZN pollutant removal from liquid wastes.

In the present research, magnetic rhamnolipid-Co/Al layered double hydroxide (MR-LDH) was synthesized to uptake methylene blue (MB) and reactive orange 16 (RO16) from aqueous solution. The main parameters, including pH, adsorbent dosage, contact time, and initial analyte concentration, were optimized to achieve the best adsorption efficiency. Accordingly, the elimination of MB on MR-LDH is improved in the basic medium due to the electrostatic interactions between the negative charge of MR-LDH and the positive charge of MB dye. In contrast, the acidic medium (pH = 3) was favored for RO16 adsorption because of hydrogen bonding between the protonated form of azo dye and protonated hydroxyl groups at the surface of MR-LDH. The calculated maximum adsorption capacities for MB and RO16 were 54.01 and 53.04 mg/g at 313 K, respectively. The Langmuir model, which assumes monolayer adsorption on the adsorbent surface, provides the best explanation for the adsorption of both dyes (R2 = 0.9991 for MB and R2 = 0.9969 for RO16). Moreover, the pseudo-second-order kinetic model best described the adsorption process for MB (R2 = 0.9970) and RO16 (R2 = 0.9941). The proposed adsorbent maintains stable adsorption performance for four consecutive cycles. After each adsorption process, MR-LDH is easily separated by an external magnet. The findings show that MR-LDH was found to be an excellent adsorbent for the removal of both cationic and anionic organic dyes from aqueous solutions.

“…MB dyes can generate intermediate substances, some of them highly toxic for their carcinogenic or mutagenic characteristics . Currently, various techniques are applied to eliminate waste coming from food or textile industries, either through biological processes (e.g., bioremediation or biological filtration) or phase change processes (e.g., sorption, , biological, advanced oxidation and, sono-photocatalytic degradation , ). Although advanced oxidation processes are very efficient in mineralizing dyes, their application is limited due to financial factors (e.g., higher costs both on chemicals and energy consumption) .…”

In this work, we studied the methylene blue (MB) dye adsorption capacity on biochar derived from residues of Prosopis juliflora seed waste, a species found in the region of the tropical dry forest of Piojó in the Department of Atlántico, Colombia. The materials were obtained by pyrolysis at temperatures of 300, 500, and 700 °C. Biochar was characterized using Fourier transform infrared (FTIR), scanning electron microscopy and energy-dispersive X-ray spectroscopy (SEM-EDX), TGA, and Brunauer–Emmett–Teller (BET) techniques. The three biochar samples presented a macroporous, rough structure with pore size between 6 and 28 μm. The largest pore surface area observed was 1.28 m 2 /g for pyrolyzed biochar produced at 500 °C, larger than that of biochar produced at 700 °C, which was 0.83 m 2 /g. The adsorption results show that the maximum percentage of MB removal was 69%. According to SEM results, the material’s pore sizes varied on average from 6 to 28 μm. We modeled MB adsorption on biomass through three different isotherm models. The Freundlich model was the best-fitting model for the removal of MB ( K F = 1.447; 1/ n = 0.352). The kinetic results showed that the pseudo-second-order model was the best-fitting model for the sorption process ( q e = 2.94 mg/g; k 2 = 0.087 g/(mg/min –1 )). Furthermore, the recycling test showed that the biochar did not change its adsorption capacity significantly. Finally, under the experimental conditions, the thermodynamic parameters indicated that the removal of MB using biochar was an endothermic and spontaneous process; all Δ G ° values ranged from −2.14 to −0.95 kJ/mol; Δ H ° was 23.54 kJ/mol and Δ S ° was 79.5 J/mol.
