Degradation of 2,4-dinitrophenol by combining sonolysis and different additives

Intensification of levofloxacin sono-degradation in a US/H2O2 system with Fe3O4 magnetic nanoparticles

“…We choose levofloxacin as a model compound because it is a commonly used FQ when treating life-threatening bacterial infections and often fails to respond to other antibiotic classes [13]. Additionally, levofloxacin cannot be effectively removed by conventional wastewater treatment processes due to its biological resistance and stability.…”

Intensification of cavitational activity using gases in different types of sonochemical reactors

“…Depending on the controlling mechanism, the selection of a suitable process intensifying additive and its loading can be decided. The use of additives including solid particles or oxidants for intensification has been demonstrated quite frequently in the recent literature [11][12][13][14] and these works have dealt with understanding the effect of different additives mainly in the conventional design of ultrasonic horn either using a model reaction or specific application such as oxidation of pollutants. Merouani et al [11] investigated the effect of different additives on the sonochemical destruction of cationic dye, Rhodamine B (RhB), in aqueous phase whereas Guo et al [12] reported a similar study for the degradation of 2,4 dinitrophenol.…”

Katekhaye et al [13] investigated the effect of additives using KI decomposition as a model reaction whereas Chakinala et al [14] used salicylic acid dosimetry for the quantification of the hydroxyl radical production.…”

Separation of p-chloronitrobenzene and o-chloronitrobenzene by selective adsorption using Silicalite-1 zeolite

“…Based on high toxicity and stability of p-and o-CNB [1], they are resistant to biodegradation. Some investigations have demonstrated that the detoxification of wastewater containing these recalcitrant chemicals can be only achieved using advanced oxidation processes (AOPs), such as photo-catalysis [2,3], Fenton oxidation [4] and ultrasonication [5,6]. It should be pointed out that decomposition of these chemicals using AOPs might result in a high treatment cost and resource waste.…”
