    Abstract: Advanced oxidation processes have drawn much attention in their application to wastewater
    treatment recently. However, it is seldom to utilize sonochemical degradation as the tool of
    environmental remediation. This study utilized 20 kHz ultrasonic irradiation as the mechanism of
    radical production. The production rate of radicals serves as the evaluation tool of sonolysis
    efficiency under the control of different pHs. Three schemes of detecting radicals were employed,
    including Fricke measurement, hydrogen peroxide indirect measurement, and 4-chlorobenzoic acid
    probe measurement. The experimental results were confirmed through different measurement
    methods. The threshold of ultrasonic intensity was also examined to form radicals under the acidic,
    neutral, or basic surroundings.
