铅（Pb2+）作为最具致癌性的重金属之一，是一类对人体危害极大的污染物，去除水中重金属离子（Pb2+）已然成为人们关注的重点和热点。三聚氰胺作为一种重要的氮杂环有机化工原料，因其具有六元氮杂环的共轭高化学稳定芳香结构，导致其反应活性较低，难以修饰加工。为拓宽三聚氰胺利用途径，通过以三聚氰胺、均苯三甲酰氯或对苯二甲酰氯、六水合硝酸锌为主要原料，制备了三聚氰胺基“双酰胺型”吸附材料，并对材料结构进行了表征，测试了其对重金属Pb2+的吸附性能。结果表明，在25℃，pH值为5时，三聚氰胺基“双酰胺型”吸附材料M3C对Pb2+的吸附量最高可达756 mg/g;M2C吸附Pb2+动力学更符合准二级动力吸附模型；Langmiur等温吸附拟合结果表明M3C的吸附性能优于M2C。
