| Abstract: | With the use of an additive and treatment of technical phosphorus by dilute nitric acid, the arsenic content in the phosphorus can be reduced from 19010-6 to 3.010-6, thus 95% of arsenic is removed. Optimal process conditions are obtained through orthogonal experiments. The results indicate that the process flow and equipment used in this method are simple, there is little danger in the process, and scaleup for commercialization is easy. |
