摘要
针对我省黄磷精制现状,研究一种黄磷除砷新方法。利用高压静电场对工业黄磷进行处理,结果显示:在电场的作用下能分离除去砷,经三级处理脱砷率可达90%以上,黄磷回收率在99.9%以上。简要介绍了此处理方法的原理及工艺。
A new technology on the removal of arsenic fi＇om yellow phosphorus was studied based on the situation of yellow phosphorus purification in Yunnan, and the principle and process was briefly introduced. Industrial yellow phosphorus was treated with high - voltage electrestatie field, and arsenic was separated. The separate rate of arsenic could be reach 90% by tertiary treatment and the recovery of yellow phosphorus could be reach 99. 9%.
