摘要：对固体材料中生物基含量的测定方法进行了综述,介绍了选择性溶解法(SDM)和^(14)C法这两种测定方法。选择性溶解法准确性相对要低,样品前处理也比较复杂且费时。^(14)C包括液体闪烁计数法和加速器质谱法,液体闪烁计数法又包括CO_2吸收法、直接液体闪烁计数法和苯合成法。CO_2吸收法简单、快速且花费低廉,但是精度较低,适用于对精度要求不高的样品;直接液体闪烁计数法样品前处理过程最简单,但对样品的要求很高,溶解于闪烁液后的溶液干扰因素多且难以消除;苯合成法具有很高的精度,但是样品前处理费时,且测定周期长。加速器质谱法快速且测定精度高,但设备费用极昂贵,在一定程度上限制了其应用。最后,对固体材料中生物基含量测定方法的各种技术发展进行了展望。
The determination methods of bio-based content in bio-based solid material, including the selective dissolution method （SDM） and 14C method, were reviewed.The precision of SDM was relatively lower, and its sample preparation was more complex and time consuming）4C method contained liquid scintillation counting（LSC） method,which included CO2 absorption method, direct LSC method and benzene synthesis, and accelerator mass spectrometry（AMS） method.CO2 absorption method was simple, fast and low cost,but it was also low precision.This method was suitable for the sample requirement for not high precision.The sample preparation of direct ESC method was the simplest in all methods, but it had a high requirement on the samples. This method had a lot of interference factors which were difficult to be eliminated.Benzene synthesis method had high precision, but the sample pretreatment took time, and the measuring period was long. Accelerator mass spectrometry was a rapid detection method and also had high precision, but the equipment was extremely expensive.These all limited its application. Finally, the prospects for their future development were also presented.
