摘要
塑料制品在环境中老化后,表面特征也会发生变化,并对其生物毒性产生很大的影响。本文采用傅立叶变换红外光谱的表征方法,对比老化前后塑料农膜的红外吸收光谱,研究塑料农膜老化过程中表面官能团的变化特征。研究发现塑料农膜表面在老化过程中发生氧化,并吸附了农药等物质,增加了塑料农膜的生态风险。
The surface feature of plastic products will change during the aging process in the environment,which will have great impact on the biological toxicity.This paper studied the changes in surface feature of plastic film during aging process by comparing the infrared absorption spectrum of the plastic films before and after aging using fourier transforms infrared spectroscopy.Our results indicated that oxidation took place on the surface of the film during the aging process and pesticides might be adsorbed,which might increase the ecological risk of plastic film.
