Offering a sustainable solution for the removal of toxic, carcinogenic, and persistent pollutants generated by industrial activities, Advanced Oxidation Processes (AOP) focuses on chemical processes based on free radical production and innovative treatment alternatives. Prepared by expert academics with deep theoretical knowledge and extensive laboratory experience in the field, this handbook addresses the effective and economic application of AOPs, as well as their optimization with critical parameters such as ecotoxicological safety and technical sustainability. Presenting technical details regarding kinetic control and process optimization with scientific rigor, the work serves as a comprehensive resource for research assistants, doctoral students, and young academics, transferring theoretical knowledge into the field of application.
