Determination of sulfur dioxide by adsorption on a solid sorbent followed by ion chromatography analysis.
A method for sampling and analysis of atmospheres for sulfur dioxide is presented. This method is based on adsorption of sulfur dioxide on an impregnated charcoal sorbent followed by desorption and analysis by ion chromatography. The precision and recovery of the sampling and analytical method were determined at 2, 1, 0.5 and 0.1 times the present OSHA standard of 5 ppm.
