Use of Inductively Coupled Plasma-Atomic Emission Spectroscopy (ICP-AES) in Three Disciplines, From Introductory Courses to Student-Research Projects.

跨学科(99)这个项目在厄勒姆学院的化学、生物和地质学的基础科学课程中纳入了用于元素分析的现代仪器。PI和团队选择了电感耦合等离子体原子发射光谱仪(ICP-AES)，因为它具有快速执行多元素分析的能力，这将允许更多的学生使用该仪器。三个预期结果指导着这个项目。其一，化学专业的学生和辅修学生正在通过在使用该仪器的标准课程中进行实验室实验，以及通过师生研究项目接触到该仪器的使用。第二，来自其他学科的学生--特别是生物学和地质学的学生--通过分析从本学科工作中获得的样本，正在获得化学信息在科学中发挥的基础作用的经验。第三，厄勒姆大学的非理科专业学生正在使用这种仪器来分析环境问题研究中获得的数据。该项目团队希望对这些非理科专业学生的理科倾向产生积极的影响。正在从几个来源改编支持使用这一仪器的原始材料。其中包括美国化学学会的书《化学在环境中的作用》(针对非科学专业的入门课程)、韦伯斯特等人的工作(因在环境化学课程中调查纯净和受污染的土壤样品中痕量金属的存在)，以及唐尼等人的工作，应得的奖#9750867(将电感耦合等离子体质谱实验改编成电感耦合等离子体发射光谱实验)。

Interdisciplinary (99) This project is incorporating modern instrumentation for elemental analysis throughout the basic science curriculum at Earlham College in chemistry, biology, and geology. The PI and team have chosen an inductively coupled plasma - atomic emission spectrometer (ICP-AES) for its rapid capacity to perform multi-elemental analysis, which will permit a larger student population to use the instrument. Three expected outcomes guide this project. One, chemistry majors and minors are gaining exposure to usage of the ICP-AES through laboratory experiments in their standard courses which use the instrument, and through student-faculty research projects. Two, students from other disciplines - in particular biology and geology - are gaining experience with the fundamental role that chemical information plays in science, by analyzing samples obtained from work in their own discipline. Third, non-science majors at Earlham are using the instrumentation to analyze data obtained in a study of environmental issues. The project team expects to positively influence the disposition of these non-science majors towards science. Source material to support the use of this instrumentation is being adapted from several sources. These include the American Chemical Society's book, "Chemistry in Context" (for the introductory course for non-science majors), the work of Webster et al., DUE award #9751439 (for investigating the presence of trace metals in pure and contaminated soil samples in an Environmental Chemistry course), and the work of Downey et al., DUE award #9750867 (adaptations of ICP-MS experiments to ICP-AES experiments).
