气体或蒸汽在固体表面上的物理吸附一直是一个很有意义的课题。通过这方面的研究,可了解固体的表面积、孔结构以及吸附层的形态、结构等。我们曾用自己建立的精密自动绝热量热计测定过水蒸汽吸附在不同的吸附剂上(不同结构的氧化铝、硅胶、分子筛等)所组成的吸附体系的热容,得到了一些有意义的结果。为考察不同吸附质在同一吸附剂吸附的影响,我们现又测定了苯吸附在氧化铝上的吸附体系的热容。 The physical adsorption of gases or vapors on solid surfaces has always been a significant issue. Through this research, we can understand the solid surface area, pore structure and adsorption layer morphology, structure and so on. We have used our own precision automatic adiabatic calorimeter to measure the heat capacity of the adsorption system composed of water vapor adsorbed on different adsorbents (different structures of alumina, silica gel, molecular sieve, etc.). Some meaningful result. To examine the effect of different adsorbates on the same adsorbent, we now measured the heat capacity of the adsorbed system of benzene adsorbed on alumina.
