摘要
详细介绍了由实验数据计算BET参数和获得比表面积值的过程,介绍了所得BET参数间应遵循的5条数学关系,并尝试进行了一些探讨。还介绍了实验标准偏差的推导过程,简要介绍了测量不确定度评定及在BET分析测试中的应用结论。文章还提醒人们在用BET模型分析金属-有机框架(MOFs)等材料时要给予特别的注意。
This study explains the process of calculating BET parameters and obtaining BET areas from experimental data. Furthermore, five mathematical relationships that should be followed among the BET parameters are discussed.This paper also introduces the derivation of the experimental standard deviation and briefly touches upon evaluating the uncertainty in measurements, along with their conclusive application to BET measurements. Finally, the paper emphasizes on providing insights on using the BET model to analyze Metal Organic Frameworks(MOFs) and other materials.
