A method and composition for generating chlorine dioxide gas comprising contacting a feedstream of chlorine gas with sodium chlorite and less than 30% by weight of a hydrated inorganic salt, i.e., one containing water of crystallization. The method increases the amount of chlorine dioxide produced by a sodium chlorite generating column, and also increases the generating lifetime of the column. The sodium chlorite and hydrated inorganic salt can be admixed in a single column, provided as separate layers within a single column, or provided in separate columns. |
