The synergetic effect of US and EO for CBZ degradation was studied.
The reaction rate apparent constant varied from 0.0033 min−1 to 0.0127 min−1.
The highest degree of synergy (33%) was recorded for 1.0 A and P = 40 W.
A relatively high degradation rate (99.5%) was recorded using the US-EO process.
The benefits of US were observed during a long-term period of treatment of CBZ.
