Abstract
This study investigates the potential of ultrasound-induced radical generation to
accelerate chemical reactions, focusing on the decomposition of hydrogen peroxide (H₂O₂).
High-frequency ultrasound creates cavitation bubbles that collapse to produce hydroxyl radicals
(•OH), significantly enhancing reaction rates. Our results demonstrate that this approach
increases the decomposition rate of H₂O₂ by 400% compared to conventional methods. The
implications extend to various applications, including optimizing chemotherapy drug activation
and improving wastewater treatment through advanced oxidation processes. Given its scalability
and cost-effectiveness, ultrasound-driven radical chemistry has the potential to transform
industrial and scientific processes.

Title
Decomposition Rates of Hydrogen Peroxide with KI and Ultrasound Vibration
Description
This dataset presents the decomposition rates of hydrogen peroxide (H₂O₂) with potassium iodide (KI), both with and without ultrasound vibration, observed at 1, 3, 5, and 10 minutes. The rate is measured by the number of gas bubbles produced, indicating the reaction speed.
Hydrogen Peroxide + KI: The decomposition rate is consistent at 10 bubbles per minute (0.17 bubbles/second) across all time intervals.
Hydrogen Peroxide + KI + Ultrasound Vibration: With ultrasound vibration, the rate increases significantly to 240 bubbles per minute (40 bubbles/second) at 3, 5, and 10 minutes.
This dataset highlights the accelerated decomposition of hydrogen peroxide when ultrasound is applied, suggesting its potential role in enhancing chemical reactions through cavitation effects.
