| 英文摘要 | A new method, without assistance of activity ratio diagram, was applied to construct the pepsilon-pH diagrams for chlorine system. The optimal pH range for generation of ClO2 by contacting Cl-2 ( g) directly with ClO2- solution is within pH 1.35-1.94, particularly within pH 1.35-4.00 only if minimizing the formation of Cl-2. It is unachievable to synthesize pure ClO2 from the reaction of Cl-2 and ClO2. Conversely, ClO2 may be present a variation of stability indifferent waters owing to the changed pepsilon and pH. ClO2 could be relatively stable if not disproportionate into ClO3, coexisting with ClO2- (pepsilon 17.63 and pH > 9.68), Cl- ( pH less than or equal to 0.92) or Cl- ( pH 0.92- 9.68). When chlorine system has already reached the ultimate equilibria, ClO2 is a stable species in strongly acid media. As the acidity decreases, ClO2 disproportionates into ClO3- and Cl-2. Aqueous Clot is unstable within the normal pH range. This work initially, theoretically elucidates the generation and stability of ClO2 by way of the pepsilon-pH diagrams. |
