本试验对四种工业活性炭的样品作了对比性研究。其中三个西德样品(C-1,C-2C-4),一个美国样品(C-5)。全部样品主要用于吸附有机蒸汽。表面及孔的研究,基本上采用77k时N_2的吸附一解吸等温线法。样品的其它特性用各种物理方法做了补充,诸如扫描电子显微镜、TGA(热解重量分析法),DTA(差示热分析仪),压汞法(水银测孔仪)及He密度法等。N_2的吸附——解吸等温线按照IUPAC(国际理论化学和应用化学联合会)推荐的分类方法可归为H_4类。N_2是在用Baratron
The test of four kinds of industrial activated carbon samples made a comparative study. Three of the West German samples (C-1, C-2C-4) and one US sample (C-5). All samples are mainly used to adsorb organic vapor. Surface and pore research, basically using 77K N_2 adsorption-desorption isotherm method. Other characteristics of the sample are complemented by various physical methods such as scanning electron microscopy, TGA (thermogravimetric analysis), DTA (differential thermal analyzer), mercury porosimetry (mercury porosimetry) and He density method . The adsorption-desorption isotherm of N 2 can be classified as H 4 according to the classification recommended by IUPAC (International Union of Theoretical and Applied Chemistry). N_2 is using Baratron
