TL;DR: In this paper, the effects of various additives such as iron (elemental, bivalent and trivalent), carbon tetrachloride, hydrogen peroxide, tert-btyl alcohol, salt (Na2SO4), sucrose and glucose on the sonochemical destruction of Rhodamine B (RhB) in aqueous phase were studied.

TL;DR: The results clearly demonstrated the significant intensification of sonolytic destruction of RhB in the presence of bicarbonate and carbonate, especially at lower dye concentrations, as carbonate radical presents a more selective reactivity towards RhB molecules than hydroxyl radical.

TL;DR: The numerical calculations of this study showed that there always exists an optimal ambient bubble radius at which the production of oxidizing species at the end of the bubble collapse attained their upper limit.

TL;DR: For the three tested dosimetries, the sonochemical efficiency was independent of liquid volume, and the main experimental parameters showing significant effect in KI oxidation dosimetry were initial KI concentration, acoustic power and pH.

TL;DR: It was concluded that, in addition to the gas solubility, the nature of the internal bubble chemistry is another parameter of a paramount importance that controls the overall sonochemical activity in aqueous solutions.
