摘要
在控制ｐＨ 条件下，定量测定了联苯胺在两种吸附剂表面的吸附等温曲线．结果表明：联苯胺在两种吸附剂表面的吸附量随着反应体系ｐＨ 的增大和加入联苯胺量的增加而增大；在相同条件下，蒙脱石的吸附能力大于铝柱层蒙脱石．文中还用热分析方法（ＴＧ，ＤＴＧ） 测定了两种氧化产物的热稳定性，并通过分析它们的傅立叶变换漫反射红外光谱（ＤＲＩＦＴ） 数据，讨论了产物的结构特征．
The interaction of montmorillonite(non pillared clay) and alumina pillared montmorillonite(Al PILC) with benzidine results in the formation of colored complexes of benzidine blue and benzidine yellow. The amount of adsorbed benzidine from an aqueous solution of benzidine dihydrochloride was measured quantitatively on the clay and the Al PILC.Under conditions of controlled pH, the amount of adsorbed benzidine by both substrates increases as the pH of the solution and the amount of added benzidine increase. The amount of adsorbed benzidine by the pillared clay is less than that on the non pillared clay under the same reaction conditions.The thermal properties of the colored complexes of benzidine with the clay and the pillared clay were measured by TGA, and their structural characteristics were examined by DRIFT spectra. From these data, the differences between benzidine blue and benzidine yellow complexes were discussed.
