• Introduction and scope
Sulfur dioxide (SO2) is a widespread pollutant gas that releases during many industrial processes [1].
SO2 has significant environmental and health implications [2], making its accurate quantification
essential. The aim of this paper was to develop a simple and efficient laboratory-scale method for the
sampling and quantification of SO2 at its source.
• Methodology
SO2, generated in the reaction between sodium metabisulfite and orthophosphoric acid, was routed
through a condenser to a recipient vessel containing an absorptive solution of sodium hydroxide. The
absorption of the SO2 was performed with a consistent gas flow rate, facilitated by the use of a vacuum
pump within the reaction system. Aqueous solution of potassium dichloroiodate(I) [3] was employed
for volumetric determination of sulfite content in the final absorptive solution.
• Results
Based on the results of sulfite content determination in the final absorptive solution, which exhibited... an
analytical recovery of SO2 ranging from 83% to 96%, the effectiveness of the proposed method is
demonstrated.
• Conclusion
According to the obtained results and the multifaceted challenges associated with the sampling of
gaseous fluids, this study can serve as a valuable guideline for the sampling of gaseous mixtures
containing SO2. Usage of a vacuum pump in the sampling system helps minimize the loss of gaseous
components in the final absorptive solution, whereas the described titrimetric method enables a simple
and efficient analytical procedure for determining SO2 content. Further research and refinement of this
method could lead to its practical application in environmental monitoring and industrial processes.
