| 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. |
