The infrared spectra of common biodegradable plastics were first collected using attenuated total reflection infra-red spectroscopy,and their characteristic functional groups were labeled.A blend of biodegradable plastic and non-de-gradable 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 pro-vides useful references for promoting the development of biodegradable plastics and the treatment of plastic pollution.
