A Green Program in Extraction and Separation Chemistry for Incorporation into the Undergraduate Curriculum

化学（12）正在开发一系列实验室实验，将对环境负责的化学分离和提取技术引入本科实验室课程。这些实验室实验是在当地政府机构的建议和参与下开发的化学绿色实验室课程的一个组成部分。该项目改编了物理化学和分析化学实验室教科书以及《化学教育杂志》的实验，并改编了莱恩地区空气污染管理局或美国环保署开发的方法。新课程的目标是：（1）为化学工业中不断变化的重点做好准备，其中源头废物管理在化学过程中发挥着越来越重要的作用;（2）培养化学专业的学生和其他人分析环境重要的现场样品，如空气和地下水。实验室课程构成了新计划的重要组成部分，因为它使化学专业的学生接触到提取和分离中的前沿问题，使用最先进的仪器，这是传统上本科化学课程中未涵盖的领域。本课程向学生介绍绿色化学，因为他们利用（1）仪器提供尖端的分析技术，如超临界流体色谱法以及更传统的HPLC能力，（2）测量环境友好溶剂通过临界点时的物理和化学性质的设施，（3）GC/ MS站，用于环境监测和有机分析。

Chemistry (12) A sequence of laboratory experiments is being developed which introduce environmentally responsible techniques of chemical separations and extractions into the undergraduate laboratory curriculum. These laboratory experiments form an integral component of a green laboratory curriculum in chemistry being developed with advice and participation from local government agencies. The project adapts experiments from physical chemistry and analytical chemistry laboratory texts and from the Journal of Chemical Education, and adapts methodology being developed by Lane Regional Air Pollution Authority or the EPA. The goals of the new curriculum are (1) to prepare chemistry majors for a changing emphasis in the chemical industry in which waste management at the source plays an ever more important role in chemical processes and (2) to train chemistry students and others in the analysis of environmentally important field samples such as air and ground water. The laboratory course constitutes an essential component of the new program since it exposes chemistry majors to cutting edge issues in extraction and separation using state of the art instrumentation in an area not traditionally covered in undergraduate chemistry curricula. Students are introduced to green chemistry as they make use of (1) instrumentation to provide cutting- edge analytical techniques such as supercritical fluid chromatography as well as more conventional HPLC capability, (2) facilities for measurements of the physical and chemical properties of environmentally friendly solvents as they pass through the critical point, and (3) a GC/ MS station for use in environmental monitoring and organic analysis.
