Paracetamol is an analgesic and antipyretic drug that is widely used by the public, with consumption reaching thousands of tons per year. Paracetamol is also known as acetaminophen, which consists of a benzene ring substituted by a hydroxyl group and a nitrogen atom. Paracetamol is not easily adsorbed or biologically degraded, leading to significant concerns about its impact on humans or the environment. Advanced Oxidation Processes (AOPs) are proven methods for treating organic compounds that are difficult to degrade. AOP utilizes free radicals to oxidize pollutant compounds, transforming them into simpler forms. The performance of the AOP method can be enhanced by combining oxidants such as ozone, hydrogen peroxide, and ultraviolet light. This study aims to evaluate the efficiency of this method in degrading paracetamol. Variations in hydrogen peroxide dosage and ozone flow rate showed differences and improvements in the efficiency and reaction rate of paracetamol removal. pH variations also yielded significant results in the efficiency and reaction rate of paracetamol removal. The optimal results were obtained with a combination of ozone, hydrogen peroxide, and ultraviolet oxidants at pH 10, achieving 100% efficiency within 60 minutes and a reaction rate constant of 6.77 k (min)-1 . Changes in parameters such as color, conductivity, turbidity, pH, and temperature in this study indicated that the treatment results using this method were not significantly different from previous research.
