摘　　要：为了去除废水中的甲基橙染料,以胱胺和色胺为原料,通过与甲醛反应成功制备了吲哚基半缩醛胺多孔材料,利用傅里叶红外光谱仪和扫描电子显微镜对其结构和形貌进行了表征,研究了吲哚基半缩醛胺多孔材料对甲基橙的吸附性能和吸附机理。结果表明:当吸附时间为20 min时,吲哚基半缩醛胺多孔材料对甲基橙的吸附量达到29.114 mg/g,吸附性能良好,其吸附过程符合准二级动力学模型。In order to remove methyl orange dye from wastewater,indole-based hemiaminal porous materials were successfully prepared by reacting cystamine and tryptamine with formaldehyde.Its structure and morphology were characterized by FT-IR and SEM.The adsorption properties and adsorption mechanism of indole-based hemiaminal porous materials for methyl orange were studied.The results show that the adsorption capacity of the indole-based hemiaminal porous materials for methyl orange reaches 29.114 mg/g when the adsorption time is 20 min.The porous materials have good adsorption performance for methyl orange.The absorption process fits a pseudo-second-order kinetic model.
