For this purpose, a series of dye/amine photoinitiators were formed using methylene blue (MB) or acridine orange (AO) as photosensitizers, and triethanolamine (TEOA), ethyl 4-(dimethylamino) benzoate (EDMAB), trioctylamine (TOA), and N,N-diméthylallylamine (DMAA) as co-initiators. The photopolymerization kinetic of the HEA monomer in the presence of proposed dye/amine systems was performed using Fourier-transform infrared spectroscopy (FTIR) analysis and the synergetic effect of the dye/amine photoinitiators systems on the photopolymerization efficiency was examined. Interestingly, (MB/EDMAB) system shows the better reactivity with a total conversion of HEA monomer.

A novel treatment method of NO in flue gas through a gas–liquid two-phase system formed by micro bubbles is proposed in this study. The system depends on the generation of hydroxyl radicals. The NO removal performance of the micro gas–liquid dispersion system induced by catalysts and O3 was explored and the reaction pathways were elucidated. Micro bubbles, Fe2+, and Mn2+ in solution improved NO removal performance significantly. Salinity and surfactants affected the removal performance of NO by altering micro bubbles. In the presence of Fe2+, the NO removal rate reached 65.2% at pH 5, 75.8% under 0.5 g/L NaCl and 82.1% under 6 mg/L sodium dodecyl sulfate. In the presence of Mn2+, the NO removal rate reached 69.2% at pH 5, 83.2% under 0.5 g/L NaCl and 92.3% under 6 mg/L sodium dodecyl sulfate. However, in the presence of both Mn2+ and Fe2+, NO conversion rate was 93.2%. The NO removal rate in the presence of O3 was further improved under the same conditions. The study provides the basis for the application and development of micro bubbles in flue gas treatments for NO removal. The results can help to solve the problems of high operating cost, large oxidant consumption, secondary pollution, and high energy consumption in traditional NO removal methods.

Kaya Laboratory of Materials Engineering and Environment: Application and Modeling, Faculty of Science, Ibn Tofail University, PO Box 133, 14000, Kenitra, Morocco Journal Article 2023 10 06 In this investigation, attempts have been made to study the corrosion inhibition properties of three new triazepine carboxylate compounds for mild steel in 1.0 M hydrochloric acid medium. The evaluation was carried out using mass loss, electrochemical impedance spectroscopy and polarization curves measurement. Impedance diagrams and Bode plots for uninhibited and inhibited systems were analyzed using Zview program. The fitted data observed trails in nearly the same pattern as the experimental results. It is showed that triazepine carboxylate compounds are very good inhibitors for mild steel corrosion in 1.0 M hydrochloric acid medium which act as mixed-type inhibitors. So, the inhibition efficiency was increased with inhibitor concentration in the order Cl–Me–CN > Me–CN > Cl–Me–CO2Et which depended on their molecular structures. Electrochemical impedance spectroscopy showed that all compounds act by the formation of a protective film at the metal surface. Surface analyses via SEM and Optical 3D profilometry were used to investigate the morphology of the steels before and after immersion in 1.0 M HCl solution containing inhibitors. The correspondence between inhibition property and molecular structure of the triazepine carboxylate compounds was investigated, using density functional theory (DFT). Experimental and DFT study was further supported by molecular dynamic simulations study.

OICC PRESS Using Box–Behnken experimental design to optimize the degradation of Basic Blue 41 dye by Fenton reaction Volume 11 (2020), IJIC Issue 1, March 2020 2023 10 06 Using Box–Behnken experimental design to optimize the degradation of Basic Blue 41 dye by Fenton reaction https://doi.org/10.1007/s40090-020-00201-5 EN Desta Solomon Environmental Engineering Stream, School of Chemical and Bio Engineering, Addis Ababa Institute of Technology, Addis Ababa University, Addis Ababa, Ethiopia 0000-0003-4817-183X Zebene Kiflie Environmental Engineering Stream, School of Chemical and Bio Engineering, Addis Ababa Institute of Technology, Addis Ababa University, Addis Ababa, Ethiopia Stijn Van Hulle Department of Green Chemistry and Technology, Gent University, Campus Kortrijk, Gent, Belgium Journal Article 2023 10 06 Degradation of a Basic Blue 41 dye using Fenton reagent was examined at laboratory scale in batch experiments using Box–Behnken statistical experiment design. Dyestuff, hydrogen peroxide (H2O2) and ferrous ion (Fe2+) concentrations were selected as independent factors. On the other hand, color and chemical oxygen demand (COD) removal were considered as the response functions. The value of coefficient of determination (R2) for both color and chemical oxygen demand removal with values 0.98 and 0.99 shows the best agreement between predicted value and experimental values. Perturbation plots indicated that iron dosage has the most effect on both color and COD removal. Normalized plot of residuals also indicated that the models were adequate to predict for both responses. Color and COD removal increased with increasing H2O2 and Fe2+ concentrations up to a certain level. High concentrations of H2O2 and Fe2+ did not result in better removal of color and COD due to hydroxyl radical being gradually consumed by both oxidant and catalyst. Percent color removal was higher than COD removal indicating the production of colorless compounds. The second-order polynomial model revealed optimal process factor ratio. The ratio of H2O2/Fe2+/dyestuff which gives a complete color removal and 95% COD removal was found to be 1195 mg/L/90 mg/L/255 mg/L.

The mesoporous material was characterized by X-ray diffraction, infrared spectroscopy, low temperature nitrogen adsorption–desorption, scanning electron microscopy, transmission electron microscopy. The low temperature nitrogen adsorption–desorption results showed that the synthesized MCFs has a diameter of 12 nm. Transmission electron microscopy revealed that the MCFs synthesized had a good honeycomb structure aperture and is conducive to the adsorption of dye macromolecule. This paper carried out the study on the adsorption of eosin Y by MCFs. The adsorption conditions of eosin Y by MCFs were optimized and the optimum adsorption conditions obtained were: MCFs:(eosin Y) = 250:1, pH 2.0, contact time 10 min at a room temperature of 22 ± 1 °C. Under the conditions, the adsorption effect was the best, the adsorption rate reached 97.95% and the adsorption capacity reached 3.96 mg/g. The research results of adsorption kinetics for the adsorption system displayed that the adsorption is the pseudo-second-order adsorption. The research results of adsorption thermodynamics showed that △G0 < 0, ΔH0 = − 40.08 kJ/mol, ΔS0 = − 51.11 J/(mol K), and the adsorption is an exothermic, spontaneous and entropy reduction reaction process. This adsorption conforms to the isothermal adsorption equation of Langmuir, belonging to a single molecular layer adsorption. All the linear correlation coefficients of the Langmuir isotherm equations fitting (R2) were greater than 0.999.
