84消毒液稳定性与均一度的基础研究与应用

Basic research and application of 84 disinfectant stability and uniformity

84消毒液的主要成分为次氯酸钠,因次氯酸钠水解生成强氧化性的次氯酸,可将还原性的菌落氧化,使微生物丧失机能,最终阻止菌群的繁殖和感染,达到杀菌的目的。84消毒液因其易制取、杀菌快、可速配的特点,被广泛应用在消毒用途中。但次氯酸钠作为一种强碱弱酸盐,其电离常数极低,分子稳定性差,并且见光、受热都会加速其分解而变为盐类,从而弱化消毒液的杀菌性,使其失效。通过寻找并研究最佳配比条件、稳定剂等,延长分解效率,是保证该类产品使用效果的关键。

The main component of 84 disinfection liquid is sodium hypochlorate,because sodium hypochlorate hydrolysis produces strong oxidation of hypochloric acid,can reduce the oxidation of the bacteria,so that microorganisms lose function,and ultimately prevent the reproduction and infection of the bacterium,to achieve the purpose of sterilization. 84 Disinfectant is widely used in disinfection applications because of its characteristics of easy-to-take,fast sterilization and speed-matching. However,sodium hypochlorite as a strong alkali weak acid,its ionization constant is very low,molecular stability is poor,and see light,heat will accelerate its decomposition and become salt,thereby weakening the sterilization of the disinfectant,making it ineffective.The key to ensure the efficiency of this kind of products is to find and study the optimum ratio condition, stabilizer, etc., to prolong the decomposition time.
