Overcoming the challenge of quantifying aged microplastic by qNMR spectroscopy

Year: 2025

Type: article

Abstract: . Additionally, degradation products in PS and PVC were quantified, providing a detailed assessment of chemical changes during aging, while PET exhibited no significant degradation. These results demonstrate that qNMR enables sensitive, reliable quantification of aged microplastics. Integration of qNMR, SEM, and FTIR offers complementary insights into microplastic aging and supports the development of robust methods for environmental microplastic monitoring.
