Nanoparticles are an increasingly important tool in chemistry research, but currently there are few opportunities for chemistry students to work with nanoparticles in undergraduate analytical courses. In this exercise, designed for an analytical or instrumental analysis lab course, students have the opportunity to work with solutions of silver nanoparticles and analyze them with two instrumental techniques. UV–vis spectrophotometry is utilized to monitor the optical behavior of silver nanoparticles over the course of the experiment. ICP-OES analysis determines the concentration of total silver species present in solution based on storage conditions. This exercise also introduces students to the concept of localized surface plasmon resonance and its role in producing the vivid colors often associated with plasmonic nanoparticles embedded in stained glass.

监测溶液中等离子纳米颗粒降解的分析方法：仪器分析实验室练习

纳米颗粒是化学研究中越来越重要的工具，但是目前化学专业的学生在本科分析课程中使用纳米颗粒的机会很少。在本练习中，该课程专为分析或仪器分析实验室课程而设计，学生有机会使用银纳米颗粒溶液并使用两种仪器技术对其进行分析。紫外可见分光光度法用于监测实验过程中银纳米颗粒的光学行为。ICP-OES分析根据存储条件确定溶液中总银离子的浓度。
