Abstract To address the disconnection between undergraduate laboratory teaching in non-chemistry majors(such as environmental,materials,and chemical engineering) and cutting-edge research and industry demands,this study designed and implemented a coagulation-sedimentation teaching experiment focused on emerging pollutants,using cerium oxide(CeO2) nanoparticles as an example.Based on constructivist and inquiry-based teaching concepts,the experiment integrated classical water treatment techniques with frontier environmental issues and introduced a large language model(LLM) to assist students in quantitatively calculating the DLVO interaction energy barriers.The purpose of this experiment is to cultivate students’ engineering practice skills,data analysis abilities,and lifelong learning habits.This paper thoroughly describes the instructional design principles,implementation processes,a multidimensional evaluation system,and in-depth teaching reflections.The practical teaching experience demonstrated that the experimental approach is simple,safe,and effective in guiding students to investigate how coagulation dosage,pH,and other factors influence the removal mechanisms of emerging pollutants.By organically combining theoretical understanding,hands-on practice,and advanced tools,the approach significantly enhances students’ abilities and interest in addressing complex practical problems.This work provides valuable insights and serves as a reference for reforming chemical laboratory teaching for non-chemistry majors such as environmental science,materials science,chemical engineering,and biomedicine within the context of new engineering disciplines.
