AI Technical Summary
Existing optical carbon dioxide gas sensors lack sufficient sensitivity and stability in detecting carbon dioxide concentration, and their fabrication methods are complex and costly, making it difficult to meet the requirements for high-precision and high-efficiency detection.
A fluorescent probe based on a Rhodamine 6G derivative was synthesized by heating and reflux reaction. The change in fluorescence intensity under ultraviolet light excitation was used to detect carbon dioxide concentration, and a standard curve was plotted using a fluorescence spectrophotometer for detection.
It achieves highly sensitive, stable, and interference-resistant carbon dioxide detection with a detection limit of 19.59 ppm. The preparation method is simple, low-cost, low-pollution, and easy to operate.
