摘要(Abstract):

聚对苯二甲酸乙二酯为目前应用最广泛的合成有机物之一。但由于其废弃物数量巨大且对大气和微生物的抵抗性很强 ,对环境造成了严重的压力。综述了PET的各种降解方法 ,着重介绍了可使PET进入生态循环 ,从根本上解决其对环境影响的生物降解方法。
Poly(ethylene terephthalate)has grown rapidly to become one of the most widely used man-made organism in the world.However,post-consumer PET products have a problem to environmental influences.This paper is a review of degradation methods of post-consumer PET.The chemical degradation and biodegradation are the main ways this field.
