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

Data 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.

Urea assisted synthesis of TiO2–CeO2 composites for photocatalytic acetaminophen degradation via simplex-centroid mixture design

Results in Engineering, 2022
We studied the effect of urea on TiO2–CeO2 and paracetamol photodegradation. The contribution of TiO2, CeO2, and urea was analyzed by simplex-centroid mixture. Solid-state combustion at 500 °C was the method of synthesis.
