Abstract
Expanded amorphous aluminum silicate (EAAS) is used as a vehicle for a chlorite salt. This vehicle, when exposed to moisture, will release chlorine dioxide (ClO ) for purposes of deodorization or microbial suppression. Thus, where a particular area or volume is to be deodorized or made less microbially contaminated, the EAAS-chlorite salt (most preferably sodium chlorite) is placed in the area or volume to be treated and moisture is permitted to interact with the material. The result of the moisture is to permit the chemical reaction (presumably acidification) of the chlorite salt to yield dioxide gas. While normal EAAS has some inherent acidity, the inherent acidity is low enough so that, even when a chloride salt is encapsulated in the EAAS and the resultant mixture exposed to moisture, ClO release is very slow and over an extended period.
