分光光度法和电位滴定法虚拟仿真实验的开发与探索

Abstract

虚拟仿真实验项目开发已成为实验教学示范中心建设工作内容之一。文章介绍了分析化学实验课程中基于LabVIEW平台的虚拟仿真项目——电位滴定法和紫外可见分光光度法测定水杨酸在水溶液中的解离常数。基于现实定量分析实验课程中实验项目的开展,对虚拟实验项目的立项安排、设计开发与实验流程等进行了介绍,并探究了虚拟仿真在实验教学中的其他相关应用。

The development of virtual simulation experiment project has become one of the contents for the construction of experimental teaching demonstration center. A virtual simulation project based on LabVIEW platform in analytical chemistry experiment course was introduced. The dissociation constant of salicylic acid in aqueous solution is determined by potentiometric titration and UV spectrophotometry. Based on the implement of the experimental project for quantitative analysis experiment course in reality, this paper introduces the implementation, arrangement, design, development and experiment process of the virtual experiment project,exploring the related applications of virtual simulation in experimental teaching.
