Beschreibung
Zusammenfassung:	A functionalized ionic liquid pyrolysis water leaching method for recovering metal from a circuit board includes the steps of detaching a waste printed circuit board, obtaining waste printed circuit board powder of a certain granularity after conducting smashing, conducting leaching, filtering and drying on the waste printed circuit board powder to obtain high-purity metal mixture powder, and diluting leaching liquid waste with distilled water and adding sulfuric acid and oxidizing agent to adjust components after being evaporated and condensed to obtain functionalized ionic liquid pyrolytic liquid again. The method is short in technological process, easy to operate, low in device requirement, high in metal recovery rate, free of pollution in the recovery process and free of secondary pollution.
