本研究采用红外光谱分析、X射线衍射分析和电泳等方法对坡缕石和海泡石吸附有机气体进行了研究。实验表明 ,这种吸附是因静电力的作用而产生的。矿物表面的吸附水可减弱静电力的作用。坡缕石、海泡石对有机气体的吸附量与气体温度、蒸气压、气体分子偶极矩、样品纯度、矿物结晶度有关。温度升高 ,气体分子热运动将加剧 ,吸附数量随之减少 ;若气体分子偶极矩加大 ,则吸附量增加 ;增大蒸气压能提高气体分子与矿物微粒间的接触频率 ,从而增强吸附 ;其他离子对Si4+ 的置换率增大 ,则静电力增强 ,对有机气体的吸附亦增强 ;样品愈纯吸附量愈大。坡缕石、海泡石对有机气体的吸附为物理吸咐。
In this study, the adsorption of organic gases on palygorskite and sepiolite was studied by infrared spectroscopy, X-ray diffraction analysis and electrophoresis. Experiments show that this adsorption is due to the role of electrostatic force generated. Adsorption of water on the mineral surface can reduce the role of electrostatic force. Palygorskite, sepiolite adsorption of organic gases and gas temperature, vapor pressure, gas molecule dipole moment, sample purity, mineral crystallinity. If the gas molecule’s dipole moment increases, the adsorption amount will increase. Increasing the vapor pressure can increase the contact frequency between the gas molecules and the mineral particles, so as to enhance the adsorption ; Other ions on the Si4 + replacement rate increases, the electrostatic force increases, the adsorption of organic gases also increased; the more pure sample the greater the amount of adsorption. Palygorskite, sepiolite adsorption of organic gases for the physical adsorption.
