Zusammenfassung:	Provided herein a process for purification of an ionic liquid from heavy metals, comprising combining heavy metal-containing ionic liquid and a sulfide source to form heavy metal sulfide, and separating said heavy metal sulfide from the ionic liquid. L'invention concerne un procédé de purification d'un liquide ionique pour éliminer des métaux lourds, lequel procédé consiste à combiner un liquide ionique contenant un métal lourd et une source de sulfure pour former du sulfure de métal lourd, et à séparer ledit sulfure de métal lourd du liquide ionique.
