研究了H_2PdCl_4和乙酸等有机酸在Al_2O_3上的吸附行为,发现H_2PdCl_4和乙酸等六种竞争吸附剂在Al_2O_3上均呈Langmuir型等温吸附,得到了H_2PdCl_4在Al_2O_3上的吸附速度式,注意到溶液的pH值和竞争吸附剂对H_2PdCl_4的吸附动力学曲线均有影响。考察了H_2PdCl_4和竞争吸附剂共存溶液的紫外吸收光谱,对H_2PdCl_4在Al_2O_3上的浸渍过程进行了讨论。
The adsorption behavior of organic acids such as H 2 PdCl 4 and acetic acid on Al 2 O 3 was studied. It was found that the competitive adsorbents such as H 2 PdCl 4 and acetic acid exhibited Langmuir isothermal adsorption on Al 2 O 3, and the adsorption rate of H 2 PdCl 4 on Al 2 O 3 was obtained. Both pH and competitive adsorbents have an effect on the adsorption kinetics of H 2 PdCl 4. The UV absorption spectra of H 2 PdCl 4 and competing adsorbent were investigated. The impregnation process of H 2 PdCl 4 on Al 2 O 3 was discussed.
