過硫酸銨為白色結(jié)晶或粉末。無氣味。干燥純品能穩(wěn)定數(shù)月，受潮時(shí)逐漸分解放出含臭氧的氧，加熱則分解出氧氣而成過硫酸銨過硫酸銨為焦硫酸銨。易溶于水，水溶液呈酸性，并在室溫中逐漸分解，在較高溫度時(shí)很快分解放出氧氣，并生成硫酸氫銨。10%過硫酸銨的配制的配置屬于溶質(zhì)的質(zhì)量分?jǐn)?shù)問題。可用下式表示：溶質(zhì)的質(zhì)量分?jǐn)?shù)=(溶質(zhì)質(zhì)量/溶液質(zhì)量)×100%。下面是詳細(xì)配置過程。
Ammonium persulfate is white crystal or powder. Odorless. The dry pure product can be stable for several months. When it is wet, it will gradually decompose and release oxygen containing ozone, and when heated, it will decompose oxygen to form ammonium persulfate, which is ammonium pyrosulfate. It is easily soluble in water. The aqueous solution is acidic and decomposes gradually at room temperature. At higher temperature, it decomposes quickly to release oxygen and produce ammonium bisulfate. The preparation of 10% ammonium persulfate belongs to the mass fraction of solute. It can be expressed by the following formula: mass fraction of solute = (solute mass / solution mass) & times; 100%。 The following is the detailed configuration process.
組份濃度： 10％（W/V）過硫酸銨
Component concentration: 10% (w / V) ammonium persulfate
配制量：
Preparation amount:
配制方法：
Preparation method:
稱取1g過硫酸銨。
Weigh 1g ammonium persulfate.
加入10mL的去離子水后攪拌溶解。
Add 10ml of deionized water and stir to dissolve.
貯存于4℃。
Store at 4 ℃.
注意：10％過硫酸胺溶液在4℃保存時(shí)間可使用2周左右，超過期限會(huì)失去催化作用。
The catalytic effect of amine solution will be lost if it is used for more than 4 weeks.
