The adsorption and immersion of different fluids on a series of carbon molecular sieves was investigated. The carbon adsorbents with significantly different micro- and mesoporosity were characterized by means of nitrogen and argon adsorption at cryogenic temperatures, vapor adsorption at 298.15 K, liquid-immersion enthalpy and pH value measurements. The polarity and chain length of the fluid molecules used for adsorption and immersion were varied to study the texture and surface polarity, the accessibility of the pore systems and the adsorption mechanisms in micro- and mesoporous adsorbents. The experimental data are evaluated with regard to correlations between adsorption and immersion measurements. The obtained results affirm once again that vapor-sorption and liquid-immersion experiments extend the characterization tool for hierarchical materials in a meaningful manner.

碳分子筛的蒸气吸附和液浸实验

研究了不同流体在一系列碳分子筛上的吸附和浸没。通过低温下的氮气和氩气吸附，298.15 K下的蒸汽吸附，液浸焓和pH值测量，对具有不同孔隙率和中孔率的碳吸附剂进行了表征。改变用于吸附和浸没的流体分子的极性和链长，以研究其结构和表面极性，孔隙系统的可及性以及在微孔和中孔吸附剂中的吸附机理。关于吸附和浸没测量之间的相关性评估了实验数据。
