Research on rapid detection of biodegradable polyester by infrared spectroscopy.

The infrared spectra of common biodegradable plastics were first collected using attenuated total reflection infrared spectroscopy, and their characteristic functional groups were labeled. A blend of biodegradable plastic and non-degradable plastic was prepared through melt blending and solution blending. The results indicated that a rapid detection method based on infrared spectroscopy was efficient and accurate in the analysis of biodegradable plastics. This study provides useful references for promoting the development of biodegradable plastics and the treatment of plastic pollution. [ABSTRACT FROM AUTHOR]
