摘要:

首先,利用衰减全反射红外光谱法采集常见生物降解塑料的红外光谱图,标记其特征官能团。随后,通过熔融共混和溶液共混得到了生物降解塑料和非降解塑料的共混物。结果表明,基于红外光谱的快速检测方法在生物降解塑料的分析中具有高效性和准确性,为推动生物降解塑料的发展以及对塑料污染的治理提供了有益的参考。

Abstract:

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.

Key words: biodegradable plastics, infrared spectroscopy, attenuated total reflection, rapid detection, blending
