[Determination of sulfur dioxide by fluorometric analysis]

Area of Science:

• Environmental Science
• Analytical Chemistry
• Atmospheric Chemistry

Background:

• Sulfur dioxide (SO2) is a major atmospheric pollutant with significant environmental and health impacts.
• Accurate and reliable monitoring of SO2 is crucial for environmental protection and regulatory compliance.

Purpose of the Study:

• To develop and optimize a fluorophotometric method for determining atmospheric sulfur dioxide (SO2) concentration.
• To investigate the feasibility of adapting this method for routine environmental monitoring.

Main Methods:

• Utilized a fluorophotometric technique to detect and quantify sulfur dioxide.
• Systematically optimized the composition and concentration of the reaction solution to enhance sensitivity and accuracy.

Main Results:

• Successfully established a fluorophotometric method for SO2 determination.
• Identified optimal conditions for the reaction solution, leading to improved measurement performance.

Conclusions:

• The developed fluorophotometric method provides a viable approach for SO2 concentration analysis.
• This method shows promise for further development into a fiber optic fluorometric system for continuous SO2 monitoring.
