The present application provides an extractant and a method for purifying copper-containing cyanide wastewater, belonging to the technical field of wastewater purification. The extractant uses an imidazole ring as the molecular backbone, and through a quaternization reaction, aliphatic chain functional groups are introduced to adjust the hydrophobic property of the extractant, ensuring that the extractant is insoluble in the inorganic aqueous phase.

The present application realizes the efficient extraction of copper in the cyanide-containing wastewater, achieving the purpose of purifying the copper-containing cyanide wastewater.
