| Abstract: | The removal technology for trace ferrite in industrial red phosphorus has been studied by adding the assistant a-gent M with the double - stage serial countercurrent reaction scheme, and the influence factors in the process have been discussed. The selected process parameters are as follows-.single- stage reaction time 4. 5"-5. 5 h,reaction temperature 88-90 "C,the assistant agent composition 1/120. Under the conditions, the removal ratio for ferrite is over 98%,the content of ferrite in the industrial red phosphorus is lower than 0. 008%. |
