Research Status and Development Direction of Defluorination Technology of Wet-process Phosphoric Acid.

The influence of fluorine on the production wet-process phosphoric acid is described. The principle, application status, advantages and disadvantages of the main defluorination process of wet phosphoric acid are reviewed. The problems existing in the current defluorination process of wet phosphoric acid are pointed out, and the future development direction is put forward in order to provide reference for the comprehensive utilization of fluorine resources in wet phosphoric acid in our country.
