Abstract
Persistent organic pollutants (POPs) are harmful chemicals that remain in the environment for a long time due to their resistance to degradation. They represent a significant challenge to sustainable development due to their enduring presence and potential for bioaccumulation in the environment. This review examines emerging technologies for POP remediation, assessing conventional methods while emphasizing the potential of innovative approaches. Advanced technologies, including nanotechnology and advanced oxidation processes (AOPs), show potential for effective, cost-efficient and environmentally friendly POP degradation. Among AOPs, methods such as UV/H 2 O 2 , Fenton’s reaction, photo-Fenton, UV/Ozone, and photocatalysis with semiconductors like TiO 2 are particularly effective in breaking down POPs into less harmful substances. Nanotechnology-based methods provide high efficiency, selectivity, and reduced environmental impact, while photocatalysis offers a sustainable and eco-friendly approach to POP degradation. To enhance remediation effectiveness, integrating innovative materials, optimized processes, and artificial intelligence (AI) is crucial. Advancements in eco-friendly nanomaterials, hybrid AOPs, and AI-driven process optimization can significantly improve degradation efficiency, selectivity, and sustainability. Future research should focus on scaling up these technologies, improving cost-effectiveness, and incorporating AI-powered smart monitoring systems for long-term environmental management. A holistic and sustainable remediation strategy must also align with circular economy principles, promote eco-friendly innovations, and address the influence of climate change on POP behavior. By fostering interdisciplinary research, policy support, and international collaboration, the development of accessible and sustainable remediation solutions can be accelerated, contributing to a cleaner environment and a healthier future for all.
