- •
Influence of persulfate (PS) on the sonochemical degradation of naphthol blue black (NBB) was examined.
- •
For the first time, the sonolytic decomposition of PS was proved.
- •
The positive effect of PS on NBB degradation decreased with increasing power.
- •
PS enhanced effect was more remarkable at 20 kHz than that observed at 585 kHz.
- •
Theoretical and experimental measurements was made for interpreting the positive effect of PS.
