In this research, wastewater containing amoxicillin antibiotic was treated using green technology "ozonation". The research was carried out with allowance for time variation (15, 30, 45, and 60 minutes), pH of wastewater (acidic, neutral, and alkaline), and ozone generator voltage (75, 150, and 225 Volt). The amoxicillin wastewater in this research was artificial. The concentration of amoxicillin was 50 ppm. Based on experimental result, the best condition of wastewater (containing amoxicillin antibiotic) ozonation was alkaline conditions with pH ≈ 10. The best percent degradation of amoxicillin antibiotic was 86.78 % with a final concentration of 6.61 ppm. The ozone generator voltage variations affect the amoxicillin removal in wastewater. The higher of ozone generator voltage, the percentage of amoxicillin removal was also increase. © Published under licence by IOP Publishing Ltd.
