Method for the separation of metal ions that are divalent or higher from strong acids or highly acidic media
The present invention relates to a method of purifying strong acids or strongly acidic media to remove di- and higher valent metal ions, which can be used within the context of the production of high-purity silica. The invention further relates to the use of special ion exchangers for carrying out t...
