水中新污染物分析创新实验的设计与实践

Design and Practice of Innovative Experiment on Analysis of Emerging Contaminants in Water

  • 摘要: 以最新的环境问题为导向设计了采用超高效液相色谱−串联质谱法(UPLC-MS/MS)测定自来水中全氟辛烷羧酸(PFOA)和全氟辛烷磺酸(PFOS)的综合创新教学实验。学生通过固相萃取(SPE)法将水中的PFOA和PFOS富集,洗脱后浓缩定容转移至样品瓶,而后用UPLC-MS/MS测定PFOA和PFOS的浓度。通过将新污染物分析技术的科研成果融入实验教学环节中,综合考查学生的实验技能及科学素养,系统全面地培养了学生利用专业知识认识环境问题的能力,提升了学生的综合素养。

     

    Abstract: Comprehensive innovative teaching experiment on analysis of perfluorooctanoic acid (PFOA) and perfluorooctane sulfonate (PFOS) in water by ultra-performance liquid chromatography tandem mass spectrometry (UPLC-MS/MS) was designed according to the latest research results. Solid-phase extraction (SPE) was used to enrich PFOA and PFOS in water, and then PFOA and PFOS were eluted, concentrated and transferred to sample vials for analysis by UPLC-MS/MS. This experiment could not only comprehensively examine students’ experimental skills and scientific literacy, but also systematically train students’ professional knowledge to understand environmental problems by combining with new research on analysis technology of emerging pollutants. Finally, the comprehensive quality of students would be enhanced.
