Hydrogen Peroxide Shelf Life Factors
On the shelf life of hydrogen peroxide
Hydrogen peroxide is also a chemical substance. Its shelf life is related to many factors and cannot be ignored.
First of all, on the storage environment. If it is placed in a cool place and protected from strong light, its decomposition is slow and the shelf life is extended. Cover light and heat can promote its decomposition. If it is exposed to the hot sun or in a high temperature place, hydrogen peroxide molecules are active and easily decompose into water and oxygen, resulting in a rapid decrease in its active components and a short shelf life.
Second talk about the material of the container. It can be kept stable in a container made of inert materials. If you use highly active materials, such as some metal containers, metal ions or catalytic hydrogen peroxide decomposition, its shelf life will be shortened. Therefore, it is often packed in glass or specific plastic containers. Such materials have weak reactions with hydrogen peroxide and can protect their quality.
Furthermore, impurities have a significant impact. Pure hydrogen peroxide has good stability and long shelf life. However, if it contains impurities, especially catalytically active impurities, such as some metal oxides, microorganisms, etc., it will speed up the decomposition process. Therefore, during preparation and storage, it is necessary to make every effort to remove impurities and keep them pure to prolong the shelf life.
In addition, the degree of sealing is also critical. If the seal is good, it is difficult for external air, moisture, etc. to enter, which can reduce the chance of reaction with foreign objects. If the seal is not good, dust particles in the air, microorganisms, etc. are easy to mix, affecting the quality of hydrogen peroxide and causing damage to the shelf life.
In summary, in order to ensure the shelf life of hydrogen peroxide, it is necessary to carefully select the storage environment, use a suitable container, control the impurity content, and ensure a good seal. In this way, hydrogen peroxide can be maintained within the valid period to maintain its chemical stability for the required use.
