The invention discloses a heavy metal ionic liquid chunk liquid film separating and recycling method. The method is implemented according to the following steps: using [BMIM]PF6 or [BEIM]PF6 as a filmsolvent and P507 as a carrier, mixing the ionic liquid and the carrier according to the volume ratio of 0.25-1.0:99.75-99.0 to obtain a liquid film phase; using HNO3 or H2SO4 as a resolution phase; mixing acetic acid and sodium acetate according to the volume ratio of 10-90:90-10 to obtain a buffer solution, and mixing the buffer solution with recycled heavy metallic salt solution according to the volume ratio of 95-85:5-15 to obtain a material liquid phase; adding the liquid film phase into a glass container, when the liquid level of the liquid film phase flows over the margin of the lower opening of a glass tube in the glass container, adding the material liquid phase into the glass container and simultaneously adding the resolution phase into the glass tube, starting a magnetic stirring apparatus to stir the liquid film phase, when the migration rate of the heavy metal ion liquid achieves over 95%, ending the stirring, and then transferring the liquid film phase and the resolutionphase into a separatory funnel for layer separation to obtain the colorless aqueous phase solution of the lower layer as the transferred heavy metal ion liquid.
