Concentrated sulfuric acid, also known as sulfuric acid, is a strong acid widely used in laboratories and industry. As a strong oxidizing agent and dehydrating agent, concentrated sulfuric acid is extremely corrosive and damaging, and misuse or improper storage may bring serious risks. Therefore, the correct storage of concentrated sulfuric acid is particularly important.

1. of concentrated sulfuric acid storage methods

1, storage environment requirements

of concentrated sulfuric acid should be stored in a clean, dry, well ventilated place, away from fire, heat, avoid direct sunlight. The storage environment temperature should not exceed 40 degrees Celsius, and the relative humidity should not exceed 85%.

2. Select the appropriate storage container
the storage container
concentrated sulfuric acid should have the characteristics of good acid resistance, anti-leakage and explosion-proof performance to prevent the leakage of concentrated sulfuric acid. recommend use the following materials of the container:

(1) reinforced polypropylene (PP) plastic barrel

reinforced polypropylene (PP) plastic barrel has strong acid resistance, alkali resistance, waterproof, leak-proof, explosion-proof and other characteristics, is the ideal container for storing concentrated sulfuric acid.

(2) Glass bottle

glass bottle has the characteristics of anti-corrosion, acid-proof, alkali-proof, transparent, etc., but sulfuric acid erodes the glass, which can easily cause the glass to become brittle, and you need to pay attention to it during storage.

(3) Stainless steel container

stainless steel container has the characteristics of strong corrosion resistance, good sealing, and high temperature resistance. It is another option for storing concentrated sulfuric acid.

3, stored in the steel cabinet

steel cabinet can be used as one of the safe storage measures of concentrated sulfuric acid, can protect the acid and the surrounding environment. By using special materials, the steel cabinet can effectively block gas and liquid leakage and ensure the safety of storage personnel.
Precautions for Use of Concentrated Sulfuric Acid in
2.

(1) Do not mix concentrated sulfuric acid with other chemical reagents;

(2) Take protective articles such as protective gloves, masks, goggles, etc. when using;

(3) When storing concentrated sulfuric acid, the packaging date, capacity, mark, warning and safety warning shall be marked;

(4) Before pouring concentrated sulfuric acid, the storage container should be cooled in water to avoid accidents caused by violent reaction;

(5) After use, the residual concentrated sulfuric acid should be sealed immediately and properly handled.

3. conclusion

concentrated sulfuric acid although in the laboratory and industry has a very wide range of applications, but we need to properly handle and store, follow the correct method of use, in order to better ensure our safety. It is suggested that laboratories, factories and other relevant units should reasonably configure the storage containers of concentrated sulfuric acid. If there are uncertain factors, it is suggested to consult relevant professionals for opinions and treatment.
