三脂肪胺-混合醇-磺化煤油萃取剂(以下简称有机相),在铀的湿法冶金工艺中常用于萃取铀。该有机相中铀的测定常用浓磷酸或碳酸盐反萃取后,直接测定水相中的铀或用石蜡凝聚有机相,用亚铁或亚钛还原-钒酸铵容量法测定。我们根据工厂常规分析的要求,详细研究了用稀盐酸将有机相中的铀反萃取到水相,用保险粉(Na_2S_2O_4)使UO_2~(2+)还原为
Triple fatty amines - mixed alcohol - sulfonated kerosene extractant (hereinafter referred to as the organic phase), uranium hydrometallurgical process commonly used in the extraction of uranium. The determination of uranium in the organic phase commonly used after the back-extraction of concentrated phosphoric acid or carbonate, the direct determination of uranium in the aqueous phase or paraffin aggregation of organic phase, with ferrous or titanium-titanium reduction - ammonium vanadate volumetric method. According to the requirements of the routine analysis of the factory, we studied in detail the use of dilute hydrochloric acid to extract the uranium from the organic phase back into the water phase and reduce the UO_2 ~ (2+) with insurance powder (Na_2S_2O_4)
