Impact/Purpose:

In this paper, the hypothesis that chlorine dioxide disinfects Bacillus spores in the biofilm/corrosion matrix better than free chlorine was tested. Results with chlorine dioxide were compared with those presented earlier by Szabo et al. (2007). Furthermore, a micro-slicing technique was performed prior to disinfection to investigate the distribution of B. globigii spores throughout the biofilm/corrosion depth. Micro-slicing was also employed during disinfection to monitor the effect of chlorine dioxide on adhered spores with depth.
