什么是過硫酸氫鉀復合鹽？
What is potassium bisulfate complex salt?
過硫酸氫鉀復合物粉是一種平衡穩(wěn)定的過氧化物、表面活性劑、有機酸及無機緩沖系統(tǒng)組成的混合物，其主要成分是過硫酸氫鉀三鹽復合物（KMPS）。具有廣譜、低毒的特點，是美國局批準注冊的一個的用于預防口蹄疫的獸用劑，并被做為機場出入境的常用劑之一，來控制外來病原的入侵。對多種致病微生物具有殺滅作用，而實際使用的水溶液毒性非常低，對人畜無害且對環(huán)境沒有殘留。
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.

過硫酸氫鉀的作用機理
Action mechanism of potassium bisulfate
過硫酸氫鉀復合粉在水中經(jīng)鏈式反應，可連續(xù)持久的產(chǎn)生小分子自由基，次氯酸，新生態(tài)氧和活性氧衍生物，氧化和氯化病原體，使菌體蛋白質(zhì)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.
產(chǎn)生的OH自由基作用于DNA，RNA的磷酸二脂鍵，干擾病原體的DNA和RNA的合成，從而殺滅病原微生物。
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.
在這個鏈式反應中，氯化鈉被KMPS三鹽復合物氧化，生成的氯氣并沒有被釋放而是與氨基磺酸（作為氯的受體）相互作用形成一個中間體復合物，然后此復合物被分解生成次氯酸，同時，這個反應是循環(huán)進行的，氯從氨基磺酸中釋放之后，用來形成更多的氯化鈉分子，為這個循環(huán)提供不斷的原料。在這個反應過程中，通過產(chǎn)生Ｈ可以起到酸劑的效果，中間產(chǎn)物CCl?和ClO可以起到鹵素類劑的作用，通過釋放O2自由基可以起到氧化物類劑的作用。
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.
過硫酸氫鉀的復合作用
Compound disinfection of potassium bisulfate
過硫酸氫鉀是個復合劑。而含氯、碘，醛類的、酚類的，生物提取物（精油）、季胺鹽類（苯扎溴銨、苯扎氯銨）、金屬類（硫酸銀、硝酸銀）劑均是單方的劑。
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.
過硫酸氫鉀產(chǎn)生H，產(chǎn)生酸，起到雙的作用；中間產(chǎn)物是氯、氧化氯，起到鹵素類作用；通過釋放氧自由基，起到氧化劑的作用。氧自由基是產(chǎn)品里非常活躍的成分，也是起非常大作用的成分。發(fā)生鏈式反應，把氯化鈉氧化成為氯，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.
這個產(chǎn)品沒有殘留，對人和動物沒有致傷畸形作用，少到現(xiàn)在為止，沒有這樣的報道。過硫酸氫鉀是國內(nèi)5代劑，無耐藥性。
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.
