Solving the problem of the 'third phase' in the extraction process by regulating the formation of micelles

Based on the theory of critical micelle , a Gemini type amide based ionic liquid system was developed to effectively extract Zr(IV) and Hf(IV) dispersed in an acidic chloride solution from the liquid phase into the organic phase through a coordination driven process. We focused on the effect of the reverse micelles formed during the extraction process of the extracted compound on the stability of the coordination system. The 'third phase' problem in the organic phase during the extraction process was analyzed from the perspective of molecular polarity. Thus, the strategy of Gemini amide ionic liquid applied to the extraction of metal ions in an acidic chloride system was improved.
