| Research Abstract |
We have been investigating development of the "hybrid-separation system" for useful metals from urban mines with environmental load-reducing. The system uses extraction with the ionic liquid and electrolytic reduction to recover mainly Pd from spent urban mines solution. To separate and recover useful metals in hydrochloric acid medium by ionic liquid with benzimidazolium as functional group has been synthesized. In previous work, it was found that these ionic liquid exhibits a quite strong extraction for some metals such as Fe(III) Pd(II) and so on. And then, extracted Fe(III) and Pd(II) can be effectively reduced using the electrolytic cell in an ionic liquid.
