Ultrafast degradation of brilliant cresyl blue under hydrodynamic cavitation based advanced oxidation processes (AOPs)

Hydrodynamic cavitation efficiently inactivates potato virus Y in water

“…Both mechanisms can have the same result, deeming the organic material non-toxic (abiotic material) or non-infectious (biotic material) [18] . This is why cavitation can be used to treat waters polluted with various contaminants including pharmaceuticals [27] , [28] , [29] , dyes [30] , pesticides [31] , [32] , cyanobacteria, fungi and bacteria (reviewed in [18] , [33] ). Only few studies examined the effect of cavitation on viruses [34] , [35] , [36] and only one of these studies used HC [36] .…”

Application of hybrid oxidative processes based on cavitation for the treatment of commercial dye industry effluents

“…Due to its higher solubility and a longer half-life than HO • radicals, sulfate radicals can be used for the degradation of a wide range of organic dye pollutants. Generally, sulfate radicals are activated thermally, by cavitation or by use of the catalyst in order to enhance the efficacy of the process [47] , [48] , [49] , [50] , [51] , [52] , [53] , [54] , [55] , [56] , [57] , [58] .…”

Degradation of Tartrazine Using Hydrodynamic Cavitation‐Based Hybrid Techniques and Fenton Chemistry

“…Hydroxyl radicals of high oxidation potential (2.80 V) are generated, which oxidize the major fraction of organic pollutants in the wastewater. AOPs like cavitation [14][15][16][17], Fenton oxidation [18,19], ozonation [20][21][22][23], photocatalysis [24], persulfate-and peroxymonosulfate-based AOPs [25][26][27], etc., and combinations thereof [15,25,28], have been explored over the years by researchers for the treatment of organic pollutants based on favorable techno-economical aspects. For example, Thanekar et al [15] have reported treatment cost of 0.21 Rs L -1 for 72.10 % chemical oxygen demand (COD) reduction in industrial effluents, using hydrodynamic cavitation (HC) combined with the Fenton reagents.…”

“…For example, Thanekar et al [15] have reported treatment cost of 0.21 Rs L -1 for 72.10 % chemical oxygen demand (COD) reduction in industrial effluents, using hydrodynamic cavitation (HC) combined with the Fenton reagents. Cako et al [28] have studied the degradation of Brilliant Cresyl Blue using HC combined with ozone and reported the treatment cost for 90 % degradation as 4.92 10 -3 USD m -3 . Boczkaj and Fernandes [29] have provided a state-of-the-art review on wastewater treatment using AOPs.…”

“…Nowadays, HC combined with AOPs is emerging as an effective technology wherein up to 100 % degradation of recalcitrant organic pollutants can be obtained [32]. For example, Cako et al [28] have demonstrated the effectiveness of HC combined with external oxidants like H 2 O 2 , ozone, and sodium persulfate for the degradation of Brilliant Cresyl Blue. HC combined with ozone was found to achieve 100 % degradation of Brilliant Cresyl Blue.…”
