Abstract : Soot has been shown to transport HCl in fires of polyvinyl chloride and polyethylene. A nitrogen gas purge of the soot easily removes 19 milligrams of HCl per gram of soot, whereas 23 milligrams of chlorine, tightly bound, remains. The spherical, amorphous soot particles formed in the combustion vary in size from 0.03 to 0.11 microns. Simple agglomeration theory suggests that the clusters grow rapidly but remain below 2.5 microns in diameter for an hour. The work implies the importance of water in transport of HCl by soot. Implications for future work are discussed. (Modified author abstract)
