Antibiotics are non-biodegradable and can remain for a long time at aquatic environments and they have a big potential bio-accumulation in the environment. The antibiotics are broadly metabolized by humans, animals and plants and they or their metabolites, after metabolization, are entered into the aquatic environment. This study aimed to optimize...

Azo dyes can lead to a number of problems in the environment due to the presence of benzene rings in their structure. Therefore, the removal of these pollutants is necessary before being discharged directly into the environment. This experimental study aimed to evaluate the degradation capability of Acid Blue 113 (AB113) by the ultrasound (US)/H 2...

The effect of ultrasound/hydrogen peroxide on the removal efficiency of 2,4-dichlorophenol (2,4-DCP) from aqueous solutions was investigated. The effects of solution pH, sonication time, H2O2 concentration, and tert-butanol (t-BuOH) concentration were also examined on process efficiency in 2,4-DCP degradation. Ultrasonic treatment at 20 kHz in comb...

... This result was consistent with the findings of other studies among Iranian university students, whose reports were between 19% and 55%. [35][36][37] Besides, in the meta-analysis study conducted by Zare et al., mental disorders were significantly heterogeneous among university students, and almost 33% of students were suspected of having mental disorders, which gradually increased over time. 26 In addition, substance use during the lifetime had a significant association with anxiety, depression, and general health of the students. ...
... After gathering the relevant articles and applying the limitations of the research strategy to factors affecting ROS formation, 18 papers were evaluated. During the revising steps for manuscript preparation in the early 2022, new found article were included it in the study ( Figure 1) [17]. ...
... Among these different types of activation, the electrochemical activation usually designated as electro-persulfate processes, were extensively carried out or practiced and considered to be the most efficient for the formation of sulfate radicals [20]. EP processes consist, in the electrochemical activation of peroxydisulfate (S 2 O 8 2− , E • = 2.01V) or peroxymonosulfate (HSO 5 − , E • = 1.82V) of producing the highly reactive radical, which presents an oxidation potential of 2.5-3.1 V [21]. Thus, to achieve the generation of SO 4 .radical, ...
... The pathway (2) involved not only attacking the chlorine of 2,4-DCP with • OH and SO 4 − • radicals but also adding hydroxyl radical onto the position of the dichlorination reaction. The intermediates including 4-chlorocatechol or chlorohydroquinone or 4chlororesorcinol are produced via a hydroxylation mechanism [65]. In pathway (3), due to the electron-donating behavior of the phenolic hydroxyl group and the electrophilicity of the radicals, the attack of • OH Table 1 The predicted toxicity value of 2,4-DCP and its degradation intermediates. ...
... Por su parte Hatamie et al. (2016) nos muestra de igual manera que las nanopartículas de hierro zero valente también puede reducir la turbidez y la demanda química de oxígeno, eliminar importantes cationes de metales pesados y aniones al mismo tiempo, siendo una grana alternativa de uso para tratamiento de aguas. Karnik et al. (2007); Sadek et al. (2021); Seid-Mohammadi et al. (2021 afirman que las nanopartículas nZVI se han distinguido de las granulares de partículas de Fe debido a la mejora en su alta movilidad y reactividad, debido a su mayor área superficial por lo cual presenta mejores resultados. Das et al. (2017) al usar Fe/ZnO NP afirma que es un tratamiento de bajo costo y con alta eficacia bajo la luz solar por lo que puede tener potencial para aplicaciones en el mundo real, para ayudar a reducir la propagación de bacterias resistentes. ...
... Sonochemical effects produced from the interaction of ultrasound with an aqueous medium have received attention in the last two decades for the degradation and complete mineralization of antibiotics and other pharmaceutical compounds. Potential merits of sonochemical methods are high degradation efficiency, a lesser amount of toxic product formation, minimum requirement of chemical/additive, ambient temperature, and pressure processing conditions (Seid-Mohammadi et al. 2019). The biodegradability and toxicity of the compounds are unaffected by the sonolysis process and highly compatible with other biological and physical processes. ...
... This method is widely used in various studies concerning the extraction, adsorption, and separation of different analytes. One of the key advantages of Taguchi analysis is its use of orthogonal arrays, which ensures that all levels and parameters receive equal importance [47][48][49][50]. This is accomplished by testing all levels of each of the other parameters at least once for each level of a specific parameter dictated by the orthogonal array method [51]. ...
... However, their complex molecular structure makes conventional treatment processes ineffective [14,15]. Studies have outlined the advantages and disadvantages of each method [16][17][18], but the major inconvenience is that these processes generate waste that must be treated or incinerated. ...
... 2,4-D, with the chemical formula of C 8 H 6 Cl 2 O 3 is a herbicide used to control woody plants and aquatic weeds and preserve non-arable areas. This herbicide is one of the most commonly used worldwide because of its polar nature and good solubility in water (Sadrnourmohamadia et al., 2017;Seid Mohammadi et al., 2014). ...
... This was inconsistent with our findings on perchlorate. A previous study found that chitosan is a natural adsorbent for perchlorate [28], and the shell of crustaceans is mainly composed of chitin, which may lead to easier interactions between the exoskeleton of crayfish and perchlorate. Then, this combination in turn leads to the highest levels of perchlorate contamination occurring in the exoskeleton of crayfish. ...
