摘　　要：该法可提取泥磷中96. 9%以上的黄磷,提取黄磷的含量可达99. 94%,杂质砷含量仅为0. 00958%,达到国家标准工业黄磷中优等品要求。Mid-temperature and vacuum extraction of yellow phosphorus from phosphorus slurry was investigated. The method was simple and had high recovery of yellow phosphorus. 96.9% of yellow phosphorus could be extracted from phosphorus slurry and the content of yellow phosphorus reached 99.9% with only 0.00958% of arsenic. The product was up to the national standard for excellent yellow phosphorus.
