| Chemical Industry-Chemical purification |
|
The area of Chemical Purification is a diverse one with regard to both the chemicals treated and the reagents used. The reasons for purification may also be quite varied and naturally depend on the manufacturing process, grade, application etc. Improvements may consist in the removal of colour, odour, minor chemical contaminants or any combination of these.
Although adsorptive materials such as activated carbon, clays, and zeolites, have been used for a number of years, their disposal or regeneration can be expensive.
Hydrogen peroxide is one of the most widely used oxidizing agents. It can be added either directly (under acidic, neutral, or alkaline conditions), in the presence of a solvent or catalyst, or in the presence of other purification agents.
In general the types of products purified in this way fall into one of eight broad cataogories as listed below:-

Advantages of peroxygens
- Peroxygen purification methods are fast, simple, and occur under mild conditions.
- Hydrogen peroxide forms only water and oxygen when its oxidising power is spent.
- Improvements can be seen in colour and odour.
