Atomic Absorption Spectroscopy Across the Undergraduate Chemistry Laboratory Curriculum

原子吸收光谱分析是化学专业本科学生在课程的各个层次都应该接触到的一种重要的元素分析方法。我们正在采用经过验证的原子吸收实验，这些实验同时使用火焰和石墨原子化程序，并将它们实施到实验室中，用于入门化学、环境化学以及仪器和实验化学。这些实验取自最近的教育文献，具有环境和现实世界的内容，因此与我们学生的经验相关，无论是专业还是非专业的学生。该仪器也被本科生用作各种研究项目的一部分。正在编写新的实验室手册，以反映对原子吸收光谱学的日益重视，这些手册可以分发给希望将原子吸收光谱学纳入其课程的其他机构。我们的学生在掌握原子吸收方面的实验和成功将通过在地方和国家会议上的演讲、在化学教育期刊上发表文章和个人接触来传播给化学教育界。

Atomic absorption spectroscopy is an important method of elemental analysis that undergraduate chemistry students should encounter at all levels of the curriculum. We are adapting proven atomic absorption experiments that use both flame and graphite atomization procedures and implementing them into the laboratories for Introductory Chemistry, Environmental Chemistry, and Instrumental and Experimental Chemistry. These experiments are taken from the recent educational literature, have an environmental, real-world content and thus are relevant to the experiences of our students, both majors and non-majors alike. The instrument is also being used by undergraduates as part of a variety of research projects. New laboratory manuals are being written to reflect the increased emphasis on atomic absorption spectroscopy and the manuals can be disseminated to other institutions wishing to incorporate atomic absorption spectroscopy into their curriculum. The experiments and the success of our students in mastering atomic absorption will be disseminated to the chemical education community through presentations at local and national meetings, publication in chemical education journals, and personal contacts.
