“…As the concentration of these solid particles increases, an increase in the number of transient cavitation events will occur due to a corresponding increase in gas nucleation sites. [55][56][57][58] We investigated this phenomena by nebulizing 9.8 kbp plasmid DNA at varying concentrations. Specifically, we monitored the concentration and rate at which I 3 À forms as well as loss of supercoiled DNA structure (Fig.…”

“…Whereas, the penetrating ability of ultrasound is very strong for any water medium and its penetrating depth can ordinarily attain to 25 -30 cm. Tuziuti et al 19 determined that the presence of the TiO2 particles contributed to an increase in bubble cavitation which promotes the transfer of the generated free radicals to the liquid bulk region as the bubble collapses. An ultrasonic irradiation might be used for formation of hydroxyl (OH • ) radical.…”

In order to effective degradation of organic dye both under visible light or ultrasonic irradiation, the MWCNTs (multiwalled carbon nanotube) deposited with Fe and TiO2 were prepared by a modified sol-gel method. The Fe/TiO2-MWCNT catalyst was characterized by surface area of BET, scanning electron microscope (SEM), Transmission Electron Microscope (TEM), X-ray diffraction (XRD), and energy dispersive X-ray (EDX) and ultraviolet-visible (UV-vis) spectroscopy. The low intensity visible light and low power ultrasound was as an irradiation source and the methylene blue (MB) was choose as the model organic dye. Then degradation experiments were carried out in present of undoped TiO2, Fe/TiO2 and Fe/TiO2-MWCNT catalysts. Through the degradation of MB solution, the results showed the feasible and potential use of Fe/TiO2-MWCNT catalyst under visible light and ultrasonic irradiation due to the enhanced formation of reactive radicals as well as the possible visible light and the increase of ultrasound-induced active surface area of the catalyst. After addition of H2O2, the MB degradation rates have been accelerated, especially with Fe/TiO2-MWCNT catalyst, in case of that the photo-Fenton reaction occurred. The sonophotocatalysis was always faster than the respective individual processes due to the more formation of reactive radicals as well as the increase of the active surface area of Fe/TiO2-MWCNT catalyst.

“…The mineralization efficiency can also be enhanced by varying the operational parameters such as initial substrate concentration, ph, catalyst loading and ultrasonic power 20 . Among the intensified,sonophotolysis involves the synergistic effects of UV irradiation and ultrasound waves towards the mineralization of the pollutants in the absence of catalysts.…”

Advanced oxidation processes (AOPs) such as fenton, ozonation, sonolysis, photocatalysis, UV photolysis, and wet air oxidation are one amongst the most suitable techniques for water and wastewater treatment. These, AOPs have also been chosen for the complete degradation of various categories of emerging pollutants that could not be managed byany conventional technologies.The mineralization is achieved by chemical reactions between the various reacting species generated and the pollutants. The present article provides avivid view of the mechanistic features of various AOPs and its possible synergisation for process enhancement to achieve better treatment efficiency. current World EnvironmentJournal Website: www.cwejournal.org
