摘要:

从环境科学专业特点出发,结合科研课题,设计了一项可用于本科教学的仪器分析开放型实验。该实验根据多环芳烃(PAHs)分子结构特点,以9-乙烯基蒽和苯乙烯为混合功能单体,利用“原位”聚合技术合成基于整体材料的固相微萃取(SPME)纤维束,并将其作为萃取介质,在优化条件下,结合高效液相色谱法(HPLC)检测环境水样中的PAHs。本实验设计并构建了一个完整的仪器分析实验流程,具体主要包括SPME纤维束的制备和表征、萃取实验条件优化、实际水样前处理和HPLC分析检测等。在教师引导下,学生开展实验前期相关知识学习、实验中期提升实验操作技能、实验后期分析数据并撰写研究报告。通过该课程全流程学习,不仅激发了学生的学习兴趣,还可培养其科学思维,提高分析和解决问题的能力,为培养新时代环境科学专业高素质人才奠定基础。

Abstract:

A research-project-based open instrumental-analysis experiment was designed for undergraduate teaching led by the attributes of an environmental science major. In this experiment, porous monolithic fibers are in-situ synthesized from 9-vinylanthracene and styrene (as a monomer mixture) based on the molecular characteristics of studied polycyclic aromatic hydrocarbons (PAHs), and then used as an extractant for solid-phase microextraction (SPME). A method for reliably monitoring PAHs in environmental water samples was developed by combining SPME with high performance liquid chromatography (HPLC). Students designed and constructed a complete experimental instrumental-analysis process, which included preparing and characterizing the monolith fibers, optimizing the SPME conditions, preparing environmental water samples, and analysis by HPLC. Guided by teachers, undergraduates learned relevant knowledge prior to performing the experiment, improved their operating skills during the experiment, analyzed data, and wrote research reports during the latter stage of the course. Undergraduates' interest is stimulated by completing the experiment, while scientific thinking, analysis, and problem-solving abilities are concurrently improved and cultivated. The present course also lays the foundation for cultivating future high-quality environmental-science talents.
