Abstract: 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.14C 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 LSC 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.
