摘要：研究了文题的萃取性能,考察了有机溶剂配比、磷酸浓度以及铁、侣、镁、钙、硅等杂质离子对萃取分离性能的影响,得到了各影响因素有利于萃取分离氟的数值范围。并初步研完了萃取过程的机理。
It was discovered that the solvent composition, the concentration of phosphoric acid, and the presence of iron, aluminium, calcium, magnesium and silicon in aqueous phase affeet extracting process. The most suitable conditions for the separation are ascertained. The mechanism of the extraction process was preliminarily studied.
