摘　　要：设计制备了一种功能性的有机膜材料,用于治理重金属离子废水的本科生实验。首先,通过化学接枝的方法将甲基丙烯酸分子修饰到聚醚砜膜表面。再通过层层组装的方法,分别将带有正负电的生物分子组装到膜表面,制备成功能性有机膜。随后考察膜材料对于重金属离子废水的治理效果。本实验提供了一种更为绿色化的重金属离子废水治理技术。通过实验课程中的动手操作,学生可以深入了解膜材料在环境治理中的重要应用潜力,激发学生了解环境治理手段的多样性,将所学与实际应用紧密联系起来。A functional organic membrane material was designed for an undergraduate experiment on treating heavy metal ion wastewater.Firstly,methacrylic acid molecules were grafted onto a polyether sulfone membrane.Then,positively and negatively charged biomolecules were assembled on the membrane surface through layer-by-layer assembly.Subsequently,the effectiveness of these membranes in treating heavy metal ion wastewater was investigated.This experiment provides a more environmentally friendly technology for treating heavy metal ion wastewater.By actively participating in this experimental course,students can gain a deep understanding of the significant potential of membrane materials in environmental management,stimulate their comprehension of diverse means for environmental governance,and establish strong connections between theoretical knowledge and practical applications.
