过硫酸铵可以在水中迅速解离，生成硫酸根离子和双氧水离子，其中硫酸根离子具有还原性，而双氧水离子具有氧化性。在水中，这两种离子之间存在着氧化还原反应。

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.

由于硫酸根离子的还原性比较弱，因此过硫酸铵只能作为弱氧化剂。然而，当过硫酸铵溶解在浓硫酸中时，可以形成二硫酸根(过硫酸根)离子，这是一种较强的氧化剂，能够将许多物质氧化。

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.

过硫酸铵能在水中起到弱氧化剂的作用，由于其分解时生成的氧化和还原离子的反应是快速的，所以过硫酸铵在一些水处理和有机合成中被广泛使用。

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.

过硫酸铵作为氧化剂和漂白剂，广泛用途于蓄电池工业，还用作聚合的引发剂、纤维工业的脱浆剂；并可用作金属及半导体材料表面处理剂、印刷线路的刻蚀剂；还用于石油开采的油层压裂，面粉和淀粉加工业、油脂工业，在照相工业上用来除去海波。

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.

过硫酸铵化学式(NH4)2S2O8，为无色单斜晶体，有时略带浅绿色，有潮解性，是过二硫酸的铵盐，过二硫酸根含有过氧基，是强氧化剂，在120℃时分解放出氧并生成焦硫酸盐，过二硫酸铵是强氧化剂,可以把Mn2+氧化为MnO4-，电解硫酸氢铵的水溶液即可制得过二硫酸铵。

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.

过硫酸铵易溶于水，化学方程式为：(NH4)2S2O8+2H2O=（可逆）=2NH4HSO4+H2O2；离子方程式：(NH4)2S2O8=2NH4++S2O82-，S2O82-+2H2O=(可逆)=2HSO4-+H2O2，HSO4-=(可逆)=H++SO42-（所以过硫酸铵溶液中除了大量的铵根离子和过二硫酸根离子外，还存在少量的硫酸氢根离子和硫酸根离子，溶液水解显酸性，加入硝酸可以抑制反应正向进行）。

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).

过硫酸铵要储存于阴凉、干燥、通风良好的库房，远离火种、热源，包装必须密封，防止受潮，应与还原剂、活性金属粉末等分开存放，切忌混储；储区应备有合适的材料收容泄漏物。您有需求就来我们网站http://qxu1539600089.my3w.com咨询吧！
