| titleOfInvention | Yellow phosphorus purification process |
| abstract | The invention discloses a yellow phosphorus purification process, which comprises the following steps: heating and stirring yellow phosphorus and hydrogen peroxide, separating the yellow phosphorus, and washing with water; II, heating and stirring the yellow phosphorus washed in the step I and the dearsenization adsorbent, separating the yellow phosphorus, and washing with water; III, adding the yellow phosphorus washed in the step II into an oxidation reinforcing agent and nitric acid, heating and stirring, separating the yellow phosphorus, and washing with water; and IV, heating and stirring the yellow phosphorus washed in the step III and the iron removal adsorbent, separating the yellow phosphorus, and washing with water. The purification process of the yellow phosphorus is simple in flow, safe to operate, high in arsenic removal rate and iron removal rate, excellent in phosphorus recovery rate and easy to realize industrial amplification. |
