Research on Experimental Preparation and Stability of Chlorine Dioxide

The paper investigated absorption solution temperature, stabilizing additive level and activation methods before application and measurement in experimental preparation of chlorine dioxide, and decomposing rate as well. The results showed that chlorine dioxide had higher percentage when absorption solution was at 0 ℃ and stabilizing additive was 1%. HCl was better activation acid than sulfuric acid and acetic acid. Its decomposing rate would become low when stabilizing additive was 1%. Low temperature and short storage time were important to solid stable chlorine dioxide. In addition, a modified test method of chlorine dioxide content was provided after comparing with common test methods.
