Adsorption of Lead Ion in Acidic Wastewater by Using Dithiocarbamic Acid Functionalized Polymer


摘要(Abstract):

采用溶剂热法合成二硫代氨基甲酸功能化二乙烯基苯-甲基丙烯酰胺聚合物吸附剂,用于处理酸性废水中的铅离子(Pb~(2+))。结果表明:该吸附剂的比表面积为230.2 m~2/g,最大平衡吸附量为342.3 mg/g,吸附平衡时间只需15 min;该吸附剂能够有效去除酸性溶液中的Pb~(2+),吸附过程符合Langmiur吸附等温线,吸附动力学符合拟二级动力学模型;经过10次循环后,该吸附剂仍保持85%的Pb~(2+)吸附率,具有较好的再生性能。
