脱除湿法磷酸中氟的实验研究

Experimental study of removing fluorine from wet-process phosphoric acid

介绍脱除湿法磷酸中氟的实验研究；探讨了除氟剂、除氟助剂、过滤助剂、反应段数、温度、时间以及工业磷酸中其它杂质等因素对除氟效率的影响；确定了适宜的除氟工艺条件。

This paper introduces the experimentalstudy of removing fluorine from wet-process phosphoricacid. The effects of defluorine agent, defluorine aids, filtering aids, number of reaction stages, temperature, timeand impurities in the industrial phosphoric acid on defluorine efficiency are discussed, and the suitable technologicalconditions of fluorine removal are also determined.
