“…These results are consistent with the previous study; they stated that most organic compounds were predominately degraded as coupled with H 2 O 2 and small pollutant concentrations with specific absorbed values at acidic conditions 13,14,24 . Based on the S/N ratio in table 3, the "Predict Taguchi result" had been conducted to find the best conditions for atrazine removal at an initial pH of 5, an atrazine concentration of 2 mg/L and an H 2 O 2 dosage of 3 mM at an absorbed dose of 6 kGy.…”

This study investigated the removal of atrazine from an aqueous solution upon electron beam irradiation from an electron accelerator. Electron beam irradiation could be considered an advanced oxidation process (AOP); these techniques have been recently applied to remove a lot of contaminants in wastewater streams. Atrazine concentrations in aqueous solutions ranging from 2 mg/L to 6 mg/L were eliminated using electron beam irradiation (2-6 kGy) at pH levels ranging from 5 to 9. The coupled electron beam and hydrogen peroxide (from 1 to 5 mM) were also investigated. This study was conducted by the Taguchi method with four variables: initial pH, atrazine concentration, H2O2 dosage, and absorbed dose to mitigate atrazine in solutions. The Taguchi process was evaluated using a Signal to Noise (S/N) ratio to find the optimal condition with the simplest design. The obtained results indicate that the absorbed dose is the most important factor, followed by the atrazine concentration and initial pH, while H2O2 seems negligible to the removal efficiency. The optimal Taguchi condition shows that the electron beam process reached the best efficiency. The best predicted atrazine eradiation was obtained 100.1% at initial pH5, H2O2 of 3 mM, atrazine concentration of 2 mg/L and absorbed dose of 6 kGy. Two confirmed experiments at optimal test conditions also performed 99.5% atrazine removal and were well fit with predicted results. Moreover, the operation cost at the optimal condition was determined approximately 3.032 $/m3, which was much cheaper than conventional treatment techniques. These obtained results highlight the potential of using the electron beam process to degrade atrazine contaminants.

“…By using an electron beam technique, Duy et al, 2019, treated three actual textile wastewaters. The degree of decolorization in samples 1, 2, and 3 increased to 93%, 98%, and 78%, respectively, when the absorbed dose was 20 kGy . In 2021, Nguyen used an electron beam technique to extract Leucomalachite Green from an aqueous solution.…”

The effects of the textile industry on the environment are now a major global concern. Many dyestuffs are toxic, carcinogenic, and non-biodegradable, which are being used in large amounts in dyeing and printing processes. Electron beam radiation is a wastewater treatment technology that is more effective than the conventional methods used for treatment of dye wastewater. The current paper presents a review on the recent advances, applications, and efficiency of electron beam irradiation and its combination with other textile effluent decolorization techniques. The purpose of this study is to accurately characterize the textile effluent electron beam treatment, to reveal its main issues, and to offer suggestions for additional growth and research. The current work examines the generation of reactive species by electron beams and their interactions with dye molecules. The mechanisms of decolorization and degradation caused by electron beam radiation have been thoroughly studied. This study also highlights the use of electron beam irradiation for the preparation of different materials and their applications in dye removal from textile effluents. This study also focuses on the use of an integrated approach of electron beam irradiation in combination with other treatment techniques for the removal of dyes from textile effluents.
