Concentrating Hydrogen Peroxide By Freezing
Concentration of hydrogen peroxide by freezing precipitation
If you want to concentrate hydrogen peroxide, the method of freezing precipitation is quite delicate. Hydrogen peroxide has strong oxidizing properties and has a wide range of uses. However, in an ordinary state, the concentration is not very good, so a method is needed to increase its concentration.
The technique of freezing precipitation is set due to the difference in the physical properties of water and hydrogen peroxide. The freezing point of water is zero degrees Celsius, while the freezing point of hydrogen peroxide is low. In a suitable low temperature environment, the water in the mixed liquid is first frozen into ice, while the hydrogen peroxide is still a liquid. At this time, the ice is separated from the hydrogen peroxide liquid, and the liquid part is taken to obtain hydrogen peroxide with a higher concentration.
When performing this operation, first place the hydrogen peroxide solution in a special container, which needs to be resistant to low temperature and has good thermal insulation properties to prevent external heat from invading. Next, place the container in a suitable low-temperature device, such as a freezer or a special low-temperature tank, and slowly cool down. Looking at the changes, when ice crystals appear, be careful to control the cooling rate, so that the water gradually turns into ice, and the hydrogen peroxide can be fully separated from the ice.
When the amount of ice formation reaches a certain level, carefully pour out the liquid hydrogen peroxide, which is then concentrated. When operating, be sure to pay attention to safety. Hydrogen peroxide is highly corrosive and oxidizing, and can cause burns in contact with skin and mucous membranes. If it encounters flammable materials, there is also a risk of fire and explosion. Therefore, the operator should be in front of protective equipment, such as gloves, goggles, etc., and the operation should be well ventilated and away from fire sources.
Therefore, from this perspective, the concentration of hydrogen peroxide by cryopreservation method, although it is delicate, it is essential for safety and cannot be ignored. Only with caution can we obtain a suitable concentration of hydrogen peroxide to meet the needs of all parties.
