Hydrogen Peroxide Stability After Opening
On the stability of hydrogen peroxide after opening
Hydrogen peroxide is also a commonly used chemical in the world. It is widely used in various industries, but after opening, the stability is often a concern for users.
When the hydrogen peroxide container is first opened, external factors disturb its stability. The first to bear the brunt is the contact with the air. Impurities, dust, or particles containing catalysis in the air, when exposed to hydrogen peroxide, it is easy to promote its decomposition. Metal ions such as iron and copper, although the amount is small, can be used as an efficient catalyst for the decomposition of hydrogen peroxide, causing it to rapidly decompose into water and oxygen.
Furthermore, changes in temperature and humidity are also related to its stability. When the temperature is high, the molecular movement of hydrogen peroxide intensifies, the activity of the chemical bonds in the molecule is enhanced, and it is easier to break, and the decomposition trend is more urgent. If the humidity is high, water vapor forms a microenvironment around hydrogen peroxide, or dissolves into it, affecting its concentration, and some impurities may be mixed with water vapor, which also accelerates the decomposition.
In addition, the material of the container containing hydrogen peroxide has a great impact on its stability. If the container material reacts chemically with hydrogen peroxide, or has catalytic activity, it will damage its stability. For example, some plastic materials, or contains soluble additives, interact with hydrogen peroxide, which intensifies the decomposition.
To maintain the stability of hydrogen peroxide after opening, there are also methods to follow. First, choose a suitable container. Glass material has relatively stable chemical properties, can reduce the reaction with hydrogen peroxide, and has good light-shielding performance, which can block the decomposition caused by light. Second, store in a cool, dry and ventilated place. Avoid high temperature, high humidity, and prevent excessive air impurities from invading. Third, try to shorten the service cycle after opening, and use it according to the required amount. It is sealed immediately after use to reduce the contact time with the outside world.
In summary, it is known that there are many factors affecting the stability of hydrogen peroxide after opening. Operators should pay attention to it, and use it properly to ensure its properties, make the best use, and avoid the harm of decomposition. It is of great significance in industries such as industry and medical care.
