摘要
对活性炭纤维现行孔结构测试标准进行了比较和分析。重点探讨了能够提高ACF材料N2吸附等温线测定、BET比表面积和孔径分布解析计算准确性的关键点。试验结果表明:BET比表面积分析的重要前提是优化用于计算的压力点选择,需要保证良好的线性和BET模型常数C为正值;ACF的孔径分布则适合采用QSDFT模型进行计算。
The current pore structures test standards of activated carbon fiber ( ACF) are compared and analyzed. The key points in the determination of N2 adsorption isotherms, the BET specific surface area and pore size distribution of ACF are discussed. The experimental results show that the important prerequisite for BET specific surface area analysis is to optimize the calculation pressure points to ensure good linearity and the positive value of C. The QSDFT model is suitable for pore size distribution of ACF.
