What is potassium bisulfate complex salt?

过硫酸氢钾复合物粉是一种平衡稳定的过氧化物、表面活性剂、有机酸及无机缓冲系统组成的混合物，其主要成分是过硫酸氢钾三盐复合物（KMPS）。具有广谱、低毒的特点，是美国局批准注册的一个的用于预防口蹄疫的兽用剂，并被做为机场出入境的常用剂之一，来控制外来病原的入侵。对多种致病微生物具有杀灭作用，而实际使用的水溶液毒性非常低，对人畜无害且对环境没有残留。

Potassium persulfate complex powder is a balanced and stable mixture of peroxide, surfactant, organic acid and inorganic buffer system, and its main component is potassium bisulfate tri salt complex (KMPS). With the characteristics of broad-spectrum and low toxicity, it is a veterinary disinfectant approved and registered by the U.S. Environmental Protection Agency to prevent foot and mouth disease, and is used as one of the commonly used disinfectants for airport entry and exit disinfection to control the invasion of foreign pathogens. It can kill a variety of pathogenic microorganisms, but the water solution used for actual disinfection has very low toxicity, is harmless to humans and animals, and has no residue on the environment.

过硫酸氢钾的理化性质

The potassium persulfate complex is a light red granular powder with lemon smell, which is easily soluble in water. The solubility in 20 ℃ water is about 65g/L. The pH value of the potassium persulfate complex powder solution with a concentration of 1% is 2.22-2.65, and the specific gravity is about 1.07.

过硫酸氢钾的作用机理

Action mechanism of potassium bisulfate

过硫酸氢钾复合粉在水中经链式反应，可连续持久的产生小分子自由基，次氯酸，新生态氧和活性氧衍生物，氧化和氯化病原体，使菌体蛋白质凝固。

After chain reaction in water, potassium bisulfate composite powder can continuously and persistently produce small molecule free radicals, hypochlorite, new ecological oxygen and active oxygen derivatives, oxidize and chlorinate pathogens, and coagulate bacterial proteins.

产生的OH自由基作用于DNA，RNA的磷酸二脂键，干扰病原体的DNA和RNA的合成，从而杀灭病原微生物。

The OH free radical produced acts on the phosphate diester bond of DNA and RNA, interfering with the synthesis of DNA and RNA of pathogens, thereby killing pathogenic microorganisms.

在这个链式反应中，氯化钠被KMPS三盐复合物氧化，生成的氯气并没有被释放而是与氨基磺酸（作为氯的受体）相互作用形成一个中间体复合物，然后此复合物被分解生成次氯酸，同时，这个反应是循环进行的，氯从氨基磺酸中释放之后，用来形成更多的氯化钠分子，为这个循环提供不断的原料。在这个反应过程中，通过产生Ｈ可以起到酸剂的效果，中间产物CCl?和ClO可以起到卤素类剂的作用，通过释放O2自由基可以起到氧化物类剂的作用。

In this chain reaction, sodium chloride is oxidized by KMPS tri salt complex, and the generated chlorine is not released, but interacts with aminosulfonic acid (as the receptor of chlorine) to form an intermediate complex, which is then decomposed to generate hypochlorite. At the same time, this reaction is carried out circularly. After chlorine is released from aminosulfonic acid, it is used to form more sodium chloride molecules, providing continuous raw materials for this cycle. In this reaction process, the acid disinfectant effect can be achieved by producing H, and the intermediate product CCl? And ClO can act as halogen disinfectants, and can act as oxide disinfectants by releasing O2 free radicals.

过硫酸氢钾的复合作用

Compound disinfection of potassium bisulfate

过硫酸氢钾是个复合剂。而含氯、碘，醛类的、酚类的，生物提取物（精油）、季胺盐类（苯扎溴铵、苯扎氯铵）、金属类（硫酸银、硝酸银）剂均是单方的剂。

Potassium bisulfate is a compound disinfectant. The disinfectants containing chlorine, iodine, aldehydes, phenols, biological extracts (essential oil), quaternary ammonium salts (benzalkonium bromide, benzalkonium chloride), and metals (silver sulfate, silver nitrate) are all single side disinfectants.

过硫酸氢钾产生H，产生酸，起到双的作用；中间产物是氯、氧化氯，起到卤素类作用；通过释放氧自由基，起到氧化剂的作用。氧自由基是产品里非常活跃的成分，也是起非常大作用的成分。发生链式反应，把氯化钠氧化成为氯，分解成次氯酸。

Potassium bisulfate produces H and acid, which plays a double disinfection role; The intermediate products are chlorine and chlorine oxide, which play the role of halogen disinfection; It acts as an oxidant by releasing oxygen free radicals. Oxygen free radicals are very active components in products and also play a very important role. A chain reaction occurs to oxidize sodium chloride into chlorine and decompose it into hypochlorite.

这个产品没有残留，对人和动物没有致伤畸形作用，少到现在为止，没有这样的报道。过硫酸氢钾是国内5代剂，无耐药性。

This product has no residue and has no injurious and deforming effect on humans and animals. At least so far, there is no such report. Potassium bisulfate is the fifth generation disinfectant in China and has no drug resistance.
