Abstract:

In this paper, a comprehensive chemistry experiment based on fluorescent probe was designed for the detection of formaldehyde. This experiment covers the fluorescence sensing mechanism based on photo-induced electron transfer, the synthesis of formaldehyde-responsive fluorescence sensor, and the preparation and application of formaldehyde-responsive test paper. Simultaneously, the research results with application prospects will be combined with the practical application of formaldehyde pollution and detection in daily life through the form of the integration of science and education, which can improve students' awareness of scientific research innovation, and apply what they learn to serve daily life.

Key words: Fluorescent sensors, Formaldehyde test paper, Naphthalimide, Comprehensive chemistry experiment
