過硫酸鈉試劑是用于制備硫酸銨的一種化工試劑,它是一種無色透明的液體,具有刺激性氣味。下面就和順酐廠家一起來看看過硫酸鈉試劑的使用、用途及正確儲存!
Sodium persulfate reagent is a chemical reagent used to prepare ammonium sulfate. It is a colorless transparent liquid with a pungent odor. Let's join the maleic anhydride manufacturer to see the use, use and correct storage of sodium persulfate reagent!
1:過硫酸鈉試劑的用途是什么?
1: What is the purpose of sodium persulfate reagent?
過硫酸鈉試劑是一種常見的化學(xué)試劑,廣泛用于工業(yè)、科研和實驗室等領(lǐng)域。該試劑具有很好的抗腐蝕性能,可以有效抑制金屬腐蝕,是制造金屬材料、化工產(chǎn)品、醫(yī)藥產(chǎn)品等的必備試劑。此外,過硫酸鈉試劑還可用于水凈化、污水處理、石油加工等工藝過程中。
Sodium persulfate reagent is a common chemical reagent, which is widely used in industry, scientific research, laboratory and other fields. The reagent has good corrosion resistance and can effectively inhibit metal corrosion. It is a necessary reagent for manufacturing metal materials, chemical products, pharmaceutical products, etc. In addition, sodium persulfate reagent can also be used in water purification, sewage treatment, oil processing and other processes.
使用過硫酸鈉試劑需要注意以下幾點:
The following points should be noted when using sodium persulfate reagent:
該試劑具有較強(qiáng)的腐蝕性,因此在使用過硫酸鈉試劑時應(yīng)注意防止與皮膚接觸;過硫酸鈉試劑易揮發(fā),因此在使用該試劑時應(yīng)注意密封并避免高溫;該試劑具有較強(qiáng)的堿性,因此在使用該試劑時應(yīng)注意避免與酸性物質(zhì)接觸;
The reagent is highly corrosive, so attention should be paid to prevent contact with skin when using sodium persulfate reagent; Sodium persulfate reagent is volatile, so when using this reagent, attention should be paid to sealing and avoiding high temperature; The reagent has strong alkalinity, so it should be avoided to contact with acidic substances when using the reagent;

2:怎么使用過硫酸鈉試劑?
2: How to use sodium persulfate reagent?
過硫酸鈉試劑可以通過多種方式使用。可以直接加入水中使用,也可以溶解后再加入水中使用。如果直接加入水中使用,一般是將試劑放入水中,然后調(diào)節(jié)PH值7左右,再逐滴加入過硫酸鈉試劑,直水中沒有堿性反應(yīng)為止。如果需要溶解后再加入水中使用,一般是將試劑放入水中,然后調(diào)節(jié)PH值7左右,再加入過硫酸鈉試劑溶解,直水中沒有堿性反應(yīng)為止。
Sodium persulfate reagent can be used in many ways. It can be directly added to water for use, or dissolved and then added to water for use. If the reagent is directly added to water for use, it is generally put into water, then adjust the PH value to about 7, and then add sodium persulfate reagent drop by drop until there is no alkaline reaction in the water. If it needs to be dissolved and then added to water for use, generally put the reagent into water, adjust the PH value to about 7, and then add sodium persulfate reagent for dissolution until there is no alkaline reaction in the water.
3:如何正確儲存過硫酸鈉試劑?
3: How to store sodium persulfate reagent correctly?
如果你購買的是干燥的過硫酸鈉試劑,在使用之前需要將其充分溶解。溶解方法是在適當(dāng)?shù)娜萜髦屑尤脒m量的水,然后加熱沸騰,待試劑充分溶解后再使用。如果使用過硫酸鈉試劑的溶液,應(yīng)當(dāng)直接使用,不要存放太久,以免影響其性能。
If you buy a dry sodium persulfate reagent, it needs to be fully dissolved before use. The dissolution method is to add a proper amount of water into a proper container, then heat it to boiling, and use it after the reagent is fully dissolved. If the solution of sodium persulfate reagent is used, it should be used directly, and should not be stored for too long, so as not to affect its performance.
