Table 3.
Frequency performance on the degradation percentage of different pharmaceuticals. For each of the studies, different concentrations, treatment times and power densities have been used and therefore, only the relative trend of the degradation percentages as a function of frequency should be compared across the different studies rather than the absolute values.
