Stability Of Solid Chlorine Dioxide

Chlorine dioxide is a new era of green disinfectant was established by World Health Organization (WHO) and the United States environmental organizations (EPA), Ministry of Health, with broad-spectrum, highly efficient, fast, and security features, widely used in water treatment, bleaching, food processing, air fresheners, and the areas of health and epidemic prevention. Compared with other disinfectants, chlorine dioxide has strong oxidation, it can cut the carbon chain of the microbial cell protein and amino acid, the cells lose their activity, so as to achieve the purpose of sterilization, and in the same time, it is not easy cause microbial resistance. Chlorine dioxide as a disinfectant can not only kill bacteria in general, but also on the typhoid fever, hepatitis A, hepatitis B, polio and the current worldwide epidemic of influenza A H1N1 influenza virus.At present, chlorine dioxide in the global application of a wide range of industries, their preparation methods, there are many, totally they are divided into electrochemical (electrolysis) and chemical, chemical Act is divided into according to the principle of oxidation reaction law and two types of reduction.According to the different use of the state, the stability chlorine dioxide products are divided into the solid and liquid chlorine dioxide. In this paper, we studyed the preparation, analysis and antimicrobial testing of the solid chlorine dioxide, according to doing a lot of research, and corresponding contrast experiments with several best-selling products on the market.Most of the stability solid chlorine dioxide disinfectant are white powder, tablet, block agent, colloid and other forms, it has many propertys, such as simple use, portable, long period, small storage space, no air pollution and so on. In this study the laboratory-made stability of powdered solid chlorine dioxide, the main component is sodium chlorite, acid, stabilizing agent and coating agent, it is a white powder, aqueous solution is yellow-green liquid. We study the chlorine dioxide test methods, and compared with test results of three other kinds of best-selling products, discussed the best testing methods. Finally, though the suspension quantitative bactericidal test, compared the bactericidal effect results with these different kinds of product and receive homologous conclusion.
