低砷黄磷的制造方法该方法在ω(ＨＮＯ3 )为 5 %～ 15 %的稀硝酸中加入工业粗黄磷和 0 .1%～ 5 .0 %的含卤素元素化合物添加剂 ,加热至 5 5～ 6 5℃ ,在 2 0 0～ 6 0 0ｒ/ｍｉｎ下搅拌 ,反应 1～ 3ｈ ,冷却后再分离出磷。具有磷回收率高、脱砷率高、工艺流程简单、反应时间短、
Method for producing low-arsenic yellow phosphorus The method adds industrial crude yellow phosphorus and 0.1-1.0% of halogen-containing compound additive in diluted nitric acid with 5% -15% of ω (HNO3) and heats it to 5 5 ~ 6 5 ℃, stirring at 200 ~ 600r / min, the reaction 1 ~ 3h, after cooling and then isolated the phosphorus. With high phosphorus recovery rate, arsenic removal rate is high, the process is simple, the reaction time is short,
