Against the backdrop of the Ministry of Education's promotion of new agricultural science construction and interdisciplinary integration, a comprehensive chemistry experiment to enhance the practical skills of students in preparing biomass functional materials and detecting pesticide residues was designed. Natural loofah was utilized as a precursor in synthesizing nitrogen-doped magnetic porous carbon materials, which were then applied in a magnetic solid-phase extraction (MSPE) technique. Subsequently, high performance liquid chromatography (HPLC) was employed to analyze and detect the phenylurea herbicide monuron in tea. The experimental process included material synthesis, characterization, optimization of the MSPE conditions, adsorption performance studies, and HPLC, reflecting its scientific, systematic nature and providing a comprehensive learning platform for students. It not only deepens student understanding of the relationship between material characterization and application, but also improves their experimental design and problem-solving capacities. Moreover, by integrating cutting-edge science, ideological and political education, and experimental training, it not only stimulates student interest in scientific research and cultivates innovative thinking and practical skills, but also strengthens their feelings of social responsibility and historical mission. This approach realizes the comprehensive educational goals of experimental training and lays the foundation for nurturing high-quality talent with a global perspective and sense of social responsibility.
在教育部推进新农科建设和学科交叉融合的背景下，设计了一个综合化学实验，以提高学生制备生物质功能材料和检测农药残留的实践技能。天然丝瓜被用作合成氮掺杂磁性多孔碳材料的前驱体，然后将其应用于磁固相萃取（MSPE）技术。随后，采用高效液相色谱（HPLC）对茶叶中的苯基脲类除草剂灭草隆进行分析检测。实验过程包括材料合成、表征、MSPE条件优化、吸附性能研究以及HPLC分析，体现了实验的科学性、系统性，为学生提供了一个综合性学习平台。它不仅加深了学生对材料表征与应用之间关系的理解，还提高了他们的实验设计和解决问题的能力。此外，通过融合前沿科学、思想政治教育和实验训练，不仅激发了学生对科研的兴趣，培养了创新思维和实践技能，还强化了他们的社会责任感和历史使命感。这种方式实现了实验训练的综合教育目标，为培养具有全球视野和社会责任感的高素质人才奠定了基础。
