- •
Low frequency ultrasound degrades ethyl paraben (EP) at the μg/L to low mg/L level.
- •
Factorial experimental design was employed to assess important operating parameters.
- •
EP concentration, time, power, pH and 2nd order interactions of EP are significant.
- •
Kinetics are between 0th and 1st order concerning EP concentration.
- •
Dealkylated and hydroxylated transformation by-products have been identified.
