Applicability of NMR spectroscopy to quantify microplastics across varying concentrations in polymer mixtures

Year: 2025

Type: article

Abstract: proves effective at intermediate concentrations. However, overlapping proton signals are observed, causing high-concentration polymers to mask low-concentration ones. While this study demonstrates low limit of quantification (LOQ) and advances in simultaneous polymer quantification, further research is needed to improve qNMR accuracy for mixed polymer samples and environmentally relevant concentrations.
