How to remove sulfuric acid from a mixed acid (55% phosphoric acid, 20% sulfuric acid, and about 25% water) while retaining phosphoric acid?
Thread Content
Those skilled experts in the group who can handle such tasks – could anyone please advise on how to remove sulfuric acid from a mixed acid solution (55% phosphoric acid, 20% sulfuric acid, and about 25% water), while retaining the phosphoric acid? Use calcium phosphate? Calcium dihydrogen phosphate? Calcium hydrogen phosphate? Is there still some other better way?
We’ll find out by doing experiments in the lab
Have you calculated the costs? Also, some phosphoric acid will be involved in the reaction as well! ~~~
{:3_49:} Sodium carbonate shows disapproval. . . .
Extraction is used for this purpose; you can purchase this technology from Wengfu, although the raffinate also contains a small amount of phosphoric acid.
Has a suitable solution been found? Or is there anyone willing to conduct experiments to see? We’re just waiting without any updates; hoping the original poster will provide more information
It is mixed with concentrated sulfuric acid and used, together with phosphate ore, to extract phosphoric acid
Looking forward...........
