聚丁二酸丁二醇酯在不同土壤环境中的降解研究

摘要

本文考察聚丁二酸丁二醇酯( PBS)在不同土壤中的降解情况，从当地取堆肥土、污泥土、垃圾土和花园土对PBS进行土埋法降解试验，通过测定降解过程中的失重率变化和对PBS降解前后表面形态观察，得出PBS在不同土壤中的降解顺序，为塑料的可降解性能的进一步研究奠定基础。%Poly( butylene succinate) ( PBS) was degraded in soil with buried method,which was compost soil, mud nutrition soil,waste soil and garden soil which selected from local resources. The experimental results were characterized by weight loss rate and the surface morphology. It concluded the order of degradation,which laid a foundation for the further study of the degradable plastics.
