摘要/Abstract

摘要： 介绍了生物基含量的定义，综述了14C含量的3种测定方法，包括加速器质谱法（AMS）、液体闪烁计数器法（LSC）、β电离法（BI），并对3种方法进行了比较分析，其中LSC更利于实际推广。

Abstract: The definition of bio-based plastics was introduced. Three determination methods of 14C content were summarized, including accelerator mass spectrometry (AMS), liquid scintillation-counter method (LSC), and Beta-ionization (BI). The advantages and disadvantages of the three kinds of method were compared. It was found that LSC was easier and more effective.

Key words: bio-based plastics, bio-based content, 14C content, testing methods
