“…The addition of a polyatomic gas will act to reduce the bubble temperature due to its higher heat capacity [260]. If the vapour of the liquid has a lower adiabatic ratio than the gas it can also influence the temperature upon collapse [261]. That is, for a liquid with a low vapour pressure, less vapour will be able to enter the bubble and cushion the collapse, therefore it occurs more violently, increasing temperature [147].…”

“…In the last few decades, sonochemical process became one of the most popular techniques for synthesis of catalysts as well as different types of materials [4][5][6][7], degradation of pollutants [8][9][10][11][12], synthesis of biodiesel [13,14], and so forth. Numerous literatures on sonochemistry have already been published [15][16][17][18] which reported the various beneficial effects of sonochemistry. The principal phenomenon behind all of these effects is the cavitation.…”

This paper presents the effects of various parameters that significantly affect the cavitation. In this study, three types of liquid mediums with different physicochemical properties were considered as the cavitation medium. The effects of various operating parameters such as temperature, pressure, initial bubble radius, dissolved gas content and so forth, were investigated in detail. The simulation results of cavitation bubble dynamics model showed a very interesting link among these parameters for production of oxidizing species. The formation of• OH radical and H 2 O 2 is considered as the results of main effects of sonochemical process. Simulation results of radial motion of cavitation bubble dynamics revealed that bubble with small initial radius gives higher sonochemical effects. This is due to the bubble with small radius can undergo many acoustic cycles before reaching its critical radius when it collapses and produces higher temperature and pressure inside the bubble. On the other hand, due to the low surface tension and high vapor pressure, organic solvents are not suitable for sonochemical reactions.

“…Ar provided complete removal after 60 min of sonication with an initial Dissolved gases influence sonolysis through three aspects. 50 First, monatomic gases typically have greater polytropic indexes γ (γ = c p /c v ) than polyatomic gases, and the higher polytropic index results in higher temperature achieved in the bubble at collapse. Second, gases with low thermal conductivities can reduce the heat dissipation, thus facilitating the increase in collapse temperatures and enhancing sonochemical reactivity.…”

Abstract:In this work, the degradation of Basic Red 29 (BR29), an azo dye, was investigated using a high-frequency ultrasonic reactor (300 kHz). The influence of several parameters such as initial substrate concentration (5-200 mg L −1 ) , pH (3-10.1), ultrasonic power (20-80 W), and nature of the dissolved gas (Ar, air, and N 2) on the degradation of BR29was assessed. Additionally, the impact of natural matrices (seawater and natural and river waters) on the degradation rate of BR29 was clarified. Degradation experiments with radical scavengers, tert-butyl alcohol and glucose, showed that BR29 degraded mainly through HO• radical attack at the gas/liquid interface of the cavitation bubbles. The degradation of the dye was strongly sensitive to the operational conditions. The natural matrices enhanced the degradation of the dye. Ultrasonic mineralization and oxidation of the dye solution was significantly enhanced by addition of a low quantity of Fe 2+ (15 mg L −1 ) .
