一、過硫酸鈉：也叫高硫酸鈉。外觀是白色晶狀粉末，無臭。能溶于水。常被用作漂白劑、氧化劑、乳液聚合促進劑。
1、 Sodium persulfate: also known as sodium persulfate. The appearance is white crystalline powder, odorless. Soluble in water. It is often used as bleaching agent, oxidant and lotion polymerization accelerator.
1、用于照相業的廢液處理，用作印刷電路板表面金屬的軟蝕劑及紡織用脫漿劑、硫化染料發色劑等。
1. It is used for the treatment of waste liquid in the photographic industry, as a soft corrosion agent for the metal on the surface of printed circuit boards, as a desizing agent for textiles, and as a colorant for vulcanized dyes.
2、用作油井壓裂液的破膠劑、電池去極化劑及有機高分子乳化聚合引發劑。照相工業用于膠片顯影、定影劑;還可用作廢液處理劑、金屬表面處理劑、印刷電路版的蝕刻劑等。
2. It is used as a gel breaker for oil well fracturing fluid, a battery depolarizer and an organic polymer emulsion polymerization initiator. Photographic industry is used for film development and fixing agent; It can also be used as waste liquid treatment agent, metal surface treatment agent, etchant for printed circuit board, etc.
3、用作漂白劑、氧化劑、乳液聚合促進劑。
3. It can be used as bleaching agent, oxidant and accelerator for lotion polymerization.
4、用于醫藥、漂白、電池，并用作化學試劑。
4. It is used in medicine, bleaching, batteries and chemical reagents.
二、過硫酸鉀：這是一種無機化合物，外觀為白色結晶狀，無氣味，有潮解性。助燃，具刺激性。常被用作漂白劑、強氧化劑、照相藥品、分析試劑、聚合促進劑等。
2、 Potassium persulfate: This is an inorganic compound with white crystalline appearance, odorless and deliquescence. It is combustion-supporting and irritant. It is often used as bleach, strong oxidant, photographic medicine, analytical reagent, polymerization accelerator, etc.
這兩種過硫酸鹽無論在外觀，性狀或用途上都有共通的地方，而這兩者的主要區別在于作為聚合促進劑時的區別。
The two persulfates have similarities in appearance, properties and use, and the main difference between them is the difference when they are used as polymerization promoters.
雖然這它們都可以作為聚合促進劑，但是二者還是有區別的：因為過硫酸鉀的的引發效果較好，所以過硫酸鉀多用于實驗室中；而過硫酸鈉相對來說其引發效果要差一些，但是其要低，所以多用于工業中。
Although both of them can be used as polymerization promoters, there are differences between the two: potassium persulfate is mostly used in the laboratory because of its better initiation effect; However, sodium persulfate has relatively poor initiating effect, but its price is lower, so it is mainly used in industrial production.
