One-step oxidation of wet-process phosphoric acid |
摘要 |
A one-step method for production of green-colored, stabilized wet-process phosphoric acid in which black-colored, wet-process phosphoric acid containing incidental metallic impurities and a carbonaceous content of less than 1000 ppm is oxidized to produce a green-colored liquid having a carbonaceous content less than 500 ppm. A typical green-colored liquid product produced by this one-step process has an emf of greater than 800 mv.
