過硫酸銨可以在水中迅速解離，生成硫酸根離子和雙氧水離子，其中硫酸根離子具有還原性，而雙氧水離子具有氧化性。在水中，這兩種離子之間存在著氧化還原反應。

Ammonium persulfate can be rapidly dissociated in water to generate sulfate ion and hydrogen peroxide ion, of which sulfate ion is reductive and hydrogen peroxide ion is oxidizing. In water, there is a Redox between these two ions.

由于硫酸根離子的還原性比較弱，因此過硫酸銨只能作為弱氧化劑。然而，當過硫酸銨溶解在濃硫酸中時，可以形成二硫酸根(過硫酸根)離子，這是一種較強的氧化劑，能夠將許多物質氧化。

Ammonium persulfate can only be used as a weak oxidant due to the weak reducibility of sulfate ion. However, when Ammonium persulfate is dissolved in concentrated sulfuric acid, it can form bisulfate (persulfate) ion, which is a strong oxidant and can oxidize many substances.

過硫酸銨能在水中起到弱氧化劑的作用，由于其分解時生成的氧化和還原離子的反應是快速的，所以過硫酸銨在一些水處理和有機合成中被廣泛使用。

Ammonium persulfate can act as a weak oxidant in water. Ammonium persulfate is widely used in some water treatment and organic synthesis because of the rapid reaction of oxidation and reduction ions generated during its decomposition.

過硫酸銨作為氧化劑和漂白劑，廣泛用途于蓄電池工業，還用作聚合的引發劑、纖維工業的脫漿劑；并可用作金屬及半導體材料表面處理劑、印刷線路的刻蝕劑；還用于石油開采的油層壓裂，面粉和淀粉加工業、油脂工業，在照相工業上用來除去海波。

Ammonium persulfate, as oxidant and bleach, is widely used in battery industry, polymerization initiator and desizing agent in fiber industry; It can also be used as a surface treatment agent for metal and semiconductor materials, as well as an etchant for printed circuits; It is also used for oil reservoir fracturing in oil extraction, flour and starch processing industry, oil and fat industry, and in the photography industry to remove sea waves.

過硫酸銨化學式(NH4)2S2O8，為無色單斜晶體，有時略帶淺綠色，有潮解性，是過二硫酸的銨鹽，過二硫酸根含有過氧基，是強氧化劑，在120℃時分解放出氧并生成焦硫酸鹽，過二硫酸銨是強氧化劑,可以把Mn2+氧化為MnO4-，電解硫酸氫銨的水溶液即可制得過二硫酸銨。

Ammonium persulfate, chemical formula (NH4) 2S2O8, is a colorless monoclinic crystal, sometimes slightly greenish, deliquescent, and is an ammonium salt of Peroxydisulfuric acid. Peroxydisulfuric acid radical contains peroxide, which is a strong oxidant. Oxygen is liberated at 120 ℃ to generate pyrosulfate. Ammonium Peroxydisulfuric acid is a strong oxidant, which can oxidize Mn2+to MnO4-. Ammonium Peroxydisulfuric acid can be prepared by electrolysis of Ammonium bisulfate aqueous solution.

過硫酸銨易溶于水，化學方程式為：(NH4)2S2O8+2H2O=（可逆）=2NH4HSO4+H2O2；離子方程式：(NH4)2S2O8=2NH4++S2O82-，S2O82-+2H2O=(可逆)=2HSO4-+H2O2，HSO4-=(可逆)=H++SO42-（所以過硫酸銨溶液中除了大量的銨根離子和過二硫酸根離子外，還存在少量的硫酸氫根離子和硫酸根離子，溶液水解顯酸性，加入硝酸可以抑制反應正向進行）。

Ammonium persulfate is easily soluble in water, and the Chemical equation is: (NH4) 2S2O8+2H2O=(reversible)=2NH4HSO4+H2O2; Ion equation: (NH4) 2S2O8=2NH4++S2O82-, S2O82-+2H2O=(reversible)=2HSO4-+H2O2, HSO4-=(reversible)=H++SO42- (so in addition to a large number of ammonium ions and Peroxydisulfuric acid ions, there are also a small amount of hydrogen sulfate ions and sulfate ions in Ammonium persulfate solution. The solution hydrolysis is acidic, and adding nitric acid can inhibit the forward reaction).

過硫酸銨要儲存于陰涼、干燥、通風良好的庫房，遠離火種、熱源，包裝必須密封，防止受潮，應與還原劑、活性金屬粉末等分開存放，切忌混儲；儲區應備有合適的材料收容泄漏物。您有需求就來我們網站http://www.ileleli.cn咨詢吧！
