以麦饭石为吸附质,采用反气相色谱法研究了载气流量、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。 The influence of the carrier gas flow, the quality of the medical stone column and the carrier gas humidity on the determination of the adsorption isotherm was investigated by using anti-gas chromatography with anti-gas chromatography. Four volatile aromatic compounds, such as benzene, Adsorption enthalpy on stone particles. The results showed that in the presence of water vapor, the adsorption of benzene and other four volatile organic compounds on the particles of the medical stone followed the ideal gas chromatographic equation, and the measured enthalpy of adsorption and the enthalpy of evaporation were close to each other.
