【摘要】： 二氧化氯是世界卫生组织(WHO)和美国环境组织(EPA)、中国卫生部等公认的新时代绿色消毒剂,具有广谱、高效、快速、安全等特点,广泛应用于水处理、漂白、食品加工、空气清新剂和卫生防疫等领域。与其他杀菌剂相比,二氧化氯是通过其自身的强氧化性,切断微生物细胞蛋白质氨基酸的碳链,使得细胞失去活性,从而达到杀菌的目的,因此不易导致微生物产生抗药性。二氧化氯作为消毒剂不仅可以对一般细菌具有杀灭作用,还可对伤寒、甲肝、乙肝、脊髓灰质炎及目前世界范围内流行的甲型H1N1流感病毒有良好的杀灭和抑制效果。目前,二氧化氯在全球各行各业中的应用相当广泛,其制备方法也有很多,主要分为电化学法(电解法)和化学法两大类,化学法又根据反应原理的不同分为氧化法和还原法两类。根据使用状态的不同,二氧化氯产品分为稳定性液体二氧化氯和稳定性固体二氧化氯两大类。本文对稳定性固体二氧化氯的制备、分析和抗菌测试等方面做了大量的研究,并与市场上几个畅销产品做了相应的对比。稳定性固体二氧化氯消毒剂大多数为白色粉末、片剂、块剂、胶体等各种形状的固体,具有使用条件简单、携带方便、有效期长、存放空间小、无空气污染等特点。本实验采用的是实验室自制的粉状稳定性固体二氧化氯,其主要成分为亚氯酸钠、固体酸、稳定剂和包覆剂,是一种白色粉末,水溶液为黄绿色液体,有刺激性气味。配置成水溶液后,研究了二氧化氯成分的测试方法,并同三种畅销产品的测试结果相对比,得出最佳测试方法。最后通过悬液定量杀菌实验,对这几种产品的杀菌效果进行研究和对比,得出相应结论。
[Abstract]:Chlorine dioxide is a new era green disinfectant recognized by the World Health Organization (WHO) and the United States Environmental Organization (EPA),). It is widely used in water treatment, bleaching and food processing because of its broad spectrum, high efficiency, speed and safety. Air fresheners and health and epidemic prevention and other areas. Compared with other fungicides, chlorine dioxide cuts off the carbon chain of protein amino acids of microbial cells through its own strong oxidation, which makes the cells lose their activity, thus achieving the purpose of bactericidal, so it is not easy for microbes to produce drug resistance. As a disinfectant, chlorine dioxide can not only kill common bacteria, but also kill and inhibit typhoid fever, hepatitis A, hepatitis B, poliomyelitis and influenza A (H1N1) virus worldwide. At present, chlorine dioxide is widely used in various industries around the world, and there are many preparation methods, which are mainly divided into two categories: electrochemical method (electrolysis) and chemical method. The chemical method is divided into two kinds according to the principle of reaction: oxidation method and reduction method. According to the state of use, chlorine dioxide products can be classified into stable liquid chlorine dioxide and stable solid chlorine dioxide. In this paper, the preparation, analysis and antimicrobial test of stable solid chlorine dioxide have been studied and compared with several best-selling products in the market. The stable solid chlorine dioxide disinfectant is mostly white powder, tablet, block agent, colloid and so on. It has the characteristics of simple use condition, convenient carrying, long validity period, small storage space, no air pollution and so on. The main components of this experiment are sodium chlorite, solid acid, stabilizer and coating agent. It is a kind of white powder and its aqueous solution is yellowish green liquid with irritating smell. The test method of chlorine dioxide was studied after it was prepared into aqueous solution, and the optimum test method was obtained by comparing with the test results of three best-selling products. Finally, through suspension quantitative germicidal experiment, the germicidal effects of these products were studied and compared, and the corresponding conclusions were drawn.
