Title:
METHOD FOR EXTRACTING PALLADIUM AND PLATINUM
Document Type and Number:
Japanese Patent JP2012149318
Kind Code:
A
Abstract:
To provide a method for effectively extracting and recovering palladium and platinum in a hydrochloric-acid acidic water solution by using a low-viscosity ion-liquid type extracting agent which has safety and in which an environmental load is small at low cost.
In the method for extracting palladium and platinum, the mixture of a poorly water-soluble ion liquid and an anion-exchange liquid are brought into contact with a hydrochloric-acid acidic water solution containing at least one of palladium and platinum, at least one of palladium and platinum is extracted to an ion liquid phase from a water phase. In this case, the poorly water-soluble ion liquid preferably contains a trialkylammonium bis(trifluoromethanesulfonyl)amide.
