Abstract:

Hydride generation-atomic fluorescence spectrometry was applied to undergraduate experimental teaching to improve the knowledge of students. In this study, hydride generation-atomic fluorescence spectrometry was performed to detect arsenic in water samples. The best experimental conditions, such as the flow rate of the carrier gas, were investigated and optimized. The detection limit, quantification limit, and precision of the method were determined. Through the study of the course, students can master the working principle and operating method of hydride generation-atomic fluorescence spectrophotometry and grasp the quantitative analysis method of detecting arsenic through hydride generation-atomic fluorescence spectrometry. In addition, students can learn how to process and analyze experimental data and understand the working principles and application fields of different types of atomic spectrometry.
