Microscopic Method to Verify the Efficiency of Removal of Organic Pollutants from Microplastic Surfaces

Majewski Kamil Artur

Civil and Environmental Engineering Reports

2023

The purification of microplastic samples is a crucial step in environmental research, aiming to remove contaminants and ensure accurate analysis. This study explores various methods for purifying microplastics, focusing on the removal of organic contaminants, specifically fulvic acids. Comparative analysis using microscopic imaging techniques was conducted to evaluate the effectiveness of these methods. The results highlight the complexities involved in microplastic purification and the challenges associated with different approaches. While some methods showed promising outcomes, such as the sonification method, it was also observed that they could potentially alter the microplastic structure. Additionally, the limitations and potential interferences of other purification methods, such as Fenton's solution, were identified. This study underscores the importance of selecting purification methods that minimize negative impacts on microplastics and ensure reliable analysis. Further research is needed to optimize purification techniques and fully understand their effects on microplastic integrity. This research contributes to the broader goal of developing robust methodologies for microplastic analysis in environmental studies.
