ABSTRACT:
Suspended black carbonaceous material contained in aqueous ammonium polyphosphate solutions, which are derived from impure wet-process phosphoric acid, is removed by mixing such a solution with ionic, water soluble, organic polymers, holding the mixture until the suspended carbonaceous material flocculates and floats to the surface, and separating the flocculated carbonaceous material from the resulting clarified ammonium polyphosphate solution.
