H2PdCl4和竞争吸附剂在Al2O3上吸附的研究

摘要/Abstract

摘要： 研究了H₂PdCl₄和乙酸等有机酸在Al₂O₃上的吸附行为,发现H₂PdCl₄和乙酸等六种竞争吸附剂在Al₂O₃上均呈Langmuir型等温吸附,得到了H₂PdCl₄在Al₂O₃上的吸附速度式,注意到溶液的pH值和竞争吸附剂对H₂PdCl₄的吸附动力学曲线均有影响。考察了H₂PdCl₄和竞争吸附剂共存溶液的紫外吸收光谱,对H₂PdCl₄在Al₂O₃上的浸渍过程进行了讨论。

Abstract: The adsorption isotherms of H₂PdCl₄ and 6 competitive adsorbates, acetic, propionic butyric, malonic, citric and maleic acids on Al₂O₃ have been investigated. They are all fiffed in with the langmuir adsorption isotherm. The results indicated that the impregnation kinetics of H₂PdCl₄ on Al₂O₃ was effected by the pH value of impregnation solution and the competitive adsorbates. Addition of competitive adsorbates was able to chauge the UV absorption spectrum of H₂PdCl₄ solution. It is suggested that there should be an interaction between H₂PdCl₄ and competitive adsorbates.
