Hydrogen peroxide can be separated from the working solution by different methods, but those most generally used involve extraction with water. The hydrogen peroxide in the working solution has a concentration between 0.8 and 1.9%w/w and efficient extractors can recover more than 95%. The concentration of hydrogen peroxide in this crude product is between 25 and 45%, and further steps are required to meet commercialgrades for purity and concentration.
