“…present in the e uent due to plasma treatment. The plasma-induced reactions and the formation of reactive species can break down or transform harmful organic compounds, reducing their toxicity to plant seeds [27]. Plasma treatment has been reported to enhance the biodegradability and reduce the toxicity of various organic pollutants [2].…”

This research focuses on the application of non-thermal plasma for treating industrial wastewater containing organic dyes. The study aims to investigate the degradation efficiency of methylene blue and textile effluent using a Microplasma setup. The experimental setup comprises of a reactor head with capillary needles, argon gas flow, and a high voltage DC power supply. The degradation of methylene blue and textile effluent is carried out at different voltages and time intervals. UV-visible analysis is conducted to measure the absorbance spectra of untreated and plasma-treated samples. The results show a decrease in absorbance with increasing plasma exposure time, indicating a reduction in methylene blue concentration. Higher applied voltages lead to more effective degradation and shorter treatment times. Textile effluent was treated at a high voltage of 20kV, which generated energetic electrons and free radicals. After a treatment period of 75 minutes, the color of the effluent intensified. UV-visible analysis of the textile effluent showed an increase in absorbance spectra with irradiation time, confirming the intensified color. FTIR spectra confirmed the presence of the C = C stretching bond with a carbonyl group (C = O) or a carboxylic acid (COOH). The phytotoxicity of untreated and Microplasma-treated textile effluent was examined by germinating tomato seeds. The results illustrated that the effluent treated for 75 minutes exhibited a higher germination rate compared to the 60-minute treatment. The untreated tomato seedlings remained the same, indicating a reduction in the toxicity of the textile effluent. Overall, non-thermal plasma treatment shows promise for efficiently removing organic dyes from industrial wastewater.

“…Moreover, some azo dyes and their analogs contain carcinogenic compounds, so treating liquid wastes containing these compounds is important to protect natural waters (4). On the other hand, the chemical treatment method requires large quantities of chemicals, and additional treatment should be taken into account for secondary protection from the reaction products, which increases the cost of the process (10). Therefore, research continues to develop an efficient and environmentally friendly new technology to treat harmful organic pollutants in industrial wastewater.…”

Adsorption equilibrium, kinetics, and thermodynamics of methylene blue dye (MB) from aqueous solutions onto activated carbon (AC) synthesized from pomegranate peel was conducted in controlled batch systems. The effects of initial MB concentration, AC particle size, contact time, and temperature on adsorption were evaluated. Under the optimized conditions (i.e., contact time 120 min, pH ∼ 5, particle size 125 µm, dye concentration 20 mg/L, temperature 333 K, and 0.5 g AC/50 mL MB solution), the removal percentages can achieve ∼ 98.28%. The nonlinear method was conducted for estimating the equilibrium and kinetic parameters, where the equilibrium data were fitted to the Langmuir isotherm model. The Langmuir isotherm suggested a maximum monolayer adsorption capacity of 5.03 mg/g at 60 °C. The pseudo-second-order kinetic model provided the best fit to the experimental data compared with the pseudo-first-order. Kinetic studies showed that the adsorption equilibrium was rapidly established, with low activation energy entailed for adsorption (Ea; 15.60 kJ/mol). Thermodynamic parameters showed that the adsorption was spontaneous (−∆G° and +∆S°), endothermic (+∆H°), and favorable at ambient conditions.

“…There are several methods for NTP generation such as dielectric barrier discharge (DBD), gliding arc discharge (GAD), corona discharge, radio frequency (RF) plasma, microwave discharge (MD), and jet plasma [13]. As reported in the literature, NTP technology is widely used for different applications [14] and especially for the degradation of pollutants from Catalysts 2020, 10, 1438 2 of 29 wastewater [15][16][17]. It is well known that the NTP process could produce active species such as O 3 , H 2 O 2…”

Non-Thermal Plasma Coupled with Catalyst for the Degradation of Water Pollutants: A Review

et al. 2020

View full text Add to dashboard Cite

Non-thermal plasma is one of the most promising technologies used for the degradation of hazardous pollutants in wastewater. Recent studies evidenced that various operating parameters influence the yield of the Non-Thermal Plasma (NTP)-based processes. In particular, the presence of a catalyst, suitably placed in the NTP reactor, induces a significant increase in process performance with respect to NTP alone. For this purpose, several researchers have studied the ability of NTP coupled to catalysts for the removal of different kind of pollutants in aqueous solution. It is clear that it is still complicated to define an optimal condition that can be suitable for all types of contaminants as well as for the various types of catalysts used in this context. However, it was highlighted that the operational parameters play a fundamental role. However, it is often difficult to understand the effect that plasma can induce on the catalyst and on the production of the oxidizing species most responsible for the degradation of contaminants. For this reason, the aim of this review is to summarize catalytic formulations coupled with non-thermal plasma technology for water pollutants removal. In particular, the reactor configuration to be adopted when NTP was coupled with a catalyst was presented, as well as the position of the catalyst in the reactor and the role of the main oxidizing species. Furthermore, in this review, a comparison in terms of degradation and mineralization efficiency was made for the different cases studied.
