在中和時氫氧化鉀與石灰可以混用嗎?

發布來源:http://www.dbc-india.com    更新時間:2021-10-19 點擊數:

我們在上中學的時候就學過可以使用堿性的物質中和酸性溶液,那么氫氧化鉀自然也是可以用來中和的,但是其實我們在生活當中還有一個經常使用的就是石灰,用石灰進行中和的應用是非常多的,那么大家可能就會有疑問了,在中和的時候兩者可以混合使用嗎。

When we were in middle school, we learned that alkaline substances can be used to neutralize acidic solutions. Naturally, potassium hydroxide can also be used for neutralization, but in fact, lime is often used in our life. There are many applications of neutralization with lime, so you may have a question. Can the two be mixed during neutralization.
廢水處理在進行中和反應的時候一般都需要使用石灰,也稱為氫氧化鈣,它是一種白色或灰白色的粉末狀固體,因為它也是強堿性質的,所以經常被用于調節廢水PH值,當然了在使用的時候還可以去除廢水當中的磷酸鹽還有大部分重金屬,而且還可以起到殺菌消毒的作用,一般在電鍍廠、化工廠、印染廠等地方也都有大量的使用。
Lime, also known as calcium hydroxide, is generally used for neutralization reaction in wastewater treatment. It is a white or gray powdered solid. Because it is also strong alkaline, it is often used to adjust the pH value of wastewater. Of course, it can also remove phosphate and most heavy metals in wastewater, It can also play the role of sterilization and disinfection. It is generally used in electroplating plants, chemical plants, printing and dyeing plants and other places.
因為在處理污水的行業里,廢水的水質也是多種多樣的,所以在進行廢水處理的時候一般都會采用兩種或兩種以上的藥劑參與中和反應,一般都會選擇化學性質相同的藥劑添加進去進行處理。
Because in the sewage treatment industry, the water quality of wastewater is also diverse, two or more agents are generally used to participate in the neutralization reaction during wastewater treatment, and agents with the same chemical properties are generally selected for treatment.
比如在進行廢水處理的時候需要使用的片堿,就是一種白色半透明片狀物,同樣也是具有強堿性的和強腐蝕性的,而且氫氧化鉀也是比較容易吸水受潮的。所以在進行廢水處理的時候可以用于調節水中PH值。一般來說雖然在進行酸堿中和的時候可以選擇使用兩種藥劑配合使用的,不過在配合使用的時候值得注意的是需要控制好相應的比例。
For example, the flake alkali used in wastewater treatment is a kind of white translucent flake, which is also highly alkaline and corrosive, and potassium hydroxide is easy to absorb water and moisture. Therefore, it can be used to adjust the pH value of water during wastewater treatment. Generally speaking, although two agents can be used together during acid-base neutralization, it is worth noting that the corresponding proportion needs to be controlled.
看過上面的介紹,我們了解到在進行中和反應的時候氫氧化鉀是可以和石灰混合使用的,不過因為兩者在性質上還是有一些不同的,所以在混合的時候一定要控制好比例。
After reading the above introduction, we know that potassium hydroxide can be mixed with lime during neutralization reaction. However, there are some differences in properties between the two, so the proportion must be controlled during mixing.
