【摘要】： 二氧化氯是世界衛(wèi)生組織(WHO)和美國環(huán)境組織(EPA)、中國衛(wèi)生部等公認的新時代綠色消毒劑,具有廣譜、高效、快速、安全等特點,廣泛應(yīng)用于水處理、漂白、食品加工、空氣清新劑和衛(wèi)生防疫等領(lǐng)域。與其他殺菌劑相比,二氧化氯是通過其自身的強氧化性,切斷微生物細胞蛋白質(zhì)氨基酸的碳鏈,使得細胞失去活性,從而達到殺菌的目的,因此不易導(dǎo)致微生物產(chǎn)生抗藥性。二氧化氯作為消毒劑不僅可以對一般細菌具有殺滅作用,還可對傷寒、甲肝、乙肝、脊髓灰質(zhì)炎及目前世界范圍內(nèi)流行的甲型H1N1流感病毒有良好的殺滅和抑制效果。 目前,二氧化氯在全球各行各業(yè)中的應(yīng)用相當廣泛,其制備方法也有很多,主要分為電化學法(電解法)和化學法兩大類,化學法又根據(jù)反應(yīng)原理的不同分為氧化法和還原法兩類。 根據(jù)使用狀態(tài)的不同,二氧化氯產(chǎn)品分為穩(wěn)定性液體二氧化氯和穩(wěn)定性固體二氧化氯兩大類。本文對穩(wěn)定性固體二氧化氯的制備、分析和抗菌測試等方面做了大量的研究,并與市場上幾個暢銷產(chǎn)品做了相應(yīng)的對比。 穩(wěn)定性固體二氧化氯消毒劑大多數(shù)為白色粉末、片劑、塊劑、膠體等各種形狀的固體,具有使用條件簡單、攜帶方便、有效期長、存放空間小、無空氣污染等特點。本實驗采用的是實驗室自制的粉狀穩(wěn)定性固體二氧化氯,其主要成分為亞氯酸鈉、固體酸、穩(wěn)定劑和包覆劑,是一種白色粉末,水溶液為黃綠色液體,有刺激性氣味。配置成水溶液后,研究了二氧化氯成分的測試方法,并同三種暢銷產(chǎn)品的測試結(jié)果相對比,得出最佳測試方法。最后通過懸液定量殺菌實驗,對這幾種產(chǎn)品的殺菌效果進行研究和對比,得出相應(yīng)結(jié)論。
[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.
