Industrially, phosphoric acid may be used in fertilizers, detergents, pharmaceuticals, water softeners.
Phosphoric acid (85 wt. % in H2O) can be used for a variety of applications, such as:
- a medium for corrosion inhibition on mild steel
- an activating agent in the preparation of activated carbon
- enhancement of electrochemical performance for energy devices
- in the development of polymeric membranes for proton exchange membrane based fuel cells
Phosphoric acid has been used as an acid solution for pH adjustment of the fermentation broth in a protocol for the acetone-butanol-ethanol (ABE) fermentation of sugars in a bioreactor.
