| titleOfInvention | Yellow phosphorus water-phase oxidizing dearsenification and water-phase oxidant recycling method |
| abstract | The invention discloses a yellow phosphorus water-phase oxidizing dearsenification and water-phase oxidant recycling method. Peracetic acid of which the concentration is 10-50% is taken as a water-phase oxidant; the yellow phosphorus is put into the water-phase oxidant to fully agitate and mix; the mass ratio of the water-phase oxidant to the yellow phosphorus is (1:1)-(10:1); the reaction temperature in the water-phase oxidant is controlled at 50-85 DEG C; the reaction time is controlled between 2 hours and 4 hours; the temperature of an arsenic water phase is controlled at 100-125 DEG C to carry out boiling deoxygenation; the time is controlled at 10-30 minutes; phosphorus pentasulfide or sulfuretted hydrogen is added to the deoxidized arsenic water phase to carry out dearsenification treatment; adding phosphorus pentoxide and hydrogen peroxide to react after filtering and exposing filtrate; the dearsenified water phase is prepared into peracetic acid; the peracetic acid is recycled in a new batch of dearsenification of arsenic yellow phosphorus after the concentration is adjusted. The method has the advantages of being convenient to operate, low in production cost, environment-friendly and safe; the water-phase oxidant can be recycled. |
