Current Approaches and Challenges in Advanced Oxidation Processes for Nanoplastic Degradation.

Area of Science:

• Environmental Science
• Chemistry
• Water Treatment

Background:

• Plastic production has increased nanoplastic (NP) pollution, creating environmental and health risks.
• Nanoplastics' small size and complex nature make them persistent pollutants.
• Effective remediation strategies are crucial for mitigating NP contamination.

Purpose of the Study:

• To review advanced oxidation processes (AOPs) for nanoplastic remediation.
• To identify research gaps in NP treatment and analysis.
• To support sustainable solutions for NP removal from water.

Main Methods:

• Analysis of existing research on ozonation, electrochemical, photocatalytic, and plasma-induced processes for NP remediation.
• Focus on processes targeting plastic particles smaller than 1 µm.
• Identification of challenges in current analytical and treatment methods.

Main Results:

• Advanced oxidation processes show potential for nanoplastic remediation.
• Significant gaps exist in effective processes and analytical methods for sub-micron NPs.
• Current methods require further development for efficient NP removal.

Conclusions:

• Further research is needed to develop robust and scalable AOPs for nanoplastic removal.
• Improved analytical techniques are essential for accurate NP detection and quantification.
• Sustainable solutions are required to address nanoplastic pollution in alignment with SDG 6.
