| 摘 要： | 以麦饭石为吸附质，采用反气相色谱法测定了载气流量、麦饭石装柱质量和载气湿度对吸附等温线测定的影响，测定了苯等４种挥发性芳香类有机物在麦饭石颗粒上的吸附焓。结果表明，在水蒸汽存在的条件下，苯等４种挥发性有机物在麦饭石颗粒上的吸附能遵循理想气相色谱方程，且测得的吸附焓和其蒸发焓较接近。

| Abstract: | Inverse gas chromatographic method (IGC) was used to determine the vapor sorption of toluene and several other volatile aromatic organic compounds on Maifan stone particles. Influences of flow rate of carrier gas, weight of particles in the volume and humidity of carrier gas were discussed. The results showed that the sorption isotherms were linear in the presence of water vapor in the carrier gas. |
