摘　　要：联苯胺被铝柱层蒙脱石及蒙脱石吸附氧化后均生成联苯胺蓝或联苯胺黄 .在控制pH条件下 ,定量测定了这两种吸附剂对联苯胺的吸附等温曲线 .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的pH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 .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 is measured quantitatively on the non pillared 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 alumina pillared clay is less than that by the non pillared clay under the same reaction conditions.
