Title:
METAL EXTRACTION AGENT, AND METHOD FOR SEPARATING AND RECOVERING METAL IONS USING SAID METAL EXTRACTION AGENT
Document Type and Number:
WIPO Patent Application WO/2024/058216
Kind Code:
A1
Abstract:
Provided is a metal extraction agent for extracting metal ions present in an aqueous phase into an oil phase, wherein nitrogen atoms positioned at both ends of a molecular chain constituting the metal extraction agent do not constitute a carbamoyl bond, and the metal extraction agent has: an unsubstituted hydrocarbon group; and any coordination functional group of coordination functional groups (G1) as a coordination functional group (α) with respect to the metal ions to be extracted, or an unsubstituted hydrocarbon group. Also provided is a method for separating and recovering metal ions, the method involving mixing an oil phase that contains the metal extraction agent with an oil phase that contains an aqueous phase containing multiple types of metal ions.
