Data on treatment of nafcillin and ampicillin antibiotics in water by sonochemistry [PDF]

open access: yesData in Brief, 2020
Ampicillin and nafcillin antibiotics were treated by high frequency ultrasound (at 375 kHz and 24.4 W). Degradations followed pseudo-first order kinetics, which constants were k: 0.0323 min−1 for AMP and k: 0.0550 min−1 for NAF.
