The Introduction of an Atomic Absorption Spectrophotometer into the Chemistry Curriculum to Strengthen Laboratory Instruction

正在使用一台瓦里安光谱AA-10B型原子吸收光谱仪和一个附带的计算机数据站，将原子吸收光谱分析的原理和技术引入若干级别的课程。正在进行的具体课程改进包括：在入门化学中引入原子吸收法，作为一种测定非处方药钠含量和测定碘化铅溶液铅含量的技术；演示原子吸收光谱仪的工作原理及其在仪器分析课程中的分析应用；以及在独立研究和夏季研究项目中使用原子吸收光谱仪。这种设备也被用于为高中生举办的一年一度的夏季化学项目。受赠人匹配来自非联邦来源的奖励。

A Varian SpectrAA-10B Atomic Absorption Spectrophotometer and an accompanying computer-based data station is being used to introduce the principles and techniques of atomic absorption spectrophotometry into the curriculum at a number of levels. Specific course improvements being made include: Introduction of the atomic absorption method into introductory chemistry as a technique for the determination of the sodium content of over- the-counter medications and for the determination of the lead content of solutions of lead iodide; Demonstration of the principles of operation of an atomic absorption spectrophotometer and its analytical applications in an instrumental analysis course; and Use of atomic absorption spectrophotometry in independednt study and in summer research programs. The equipment is also being used in the annual summer chemistry program for advanced high school students. The grantee is matching the award from non-Federal sources.
