Purifying Hydrogen Peroxide Methods
The method of purifying hydrogen peroxide
If you want to purify hydrogen peroxide, there are various methods.
First, you can use distillation. With the difference between the boiling points of hydrogen peroxide and its impurities, temperature-controlled distillation. However, hydrogen peroxide is easy to decompose when heated, so when distilling, you need to pay attention to the temperature, and it is appropriate to use vacuum distillation to reduce its boiling point to prevent its decomposition, so that hydrogen peroxide can be separated from impurities to achieve the purpose of purification.
Second, the method of extraction can be applied. Choose an appropriate extractant, which is insoluble with hydrogen peroxide and has excellent solubility to impurities. The mixture containing hydrogen peroxide is mixed with the extractant and shaken to dissolve the impurities into the extractant, and then the liquid is separated, and the extractant layer containing impurities is discarded to obtain pure hydrogen peroxide.
Third, the method of chemical precipitation can be adopted. If the impurities are substances that can form precipitation with specific reagents, select an appropriate precipitant and add it to the mixture to make the impurities react with it to form precipitation. Following the method of filtration, remove the precipitation and retain the filtrate, the hydrogen peroxide can also be purified.
Fourth, the method of ion exchange can also be used. With ion exchange resin, it has the ability to selectively adsorb specific ions. The solution containing hydrogen peroxide flows through the ion exchange resin column, the resin absorbs the impurity ions in the solution, and the solution out of the column is the purified hydrogen peroxide.
There are many ways to purify hydrogen peroxide. When the nature of impurities, the use of hydrogen peroxide and the required purity, the optimal method is selected to achieve a good purification effect.
