How to make liquid spheres coalesce faster?
I want to extract I2 from aqueous mixture using DCM. The mixture has I2, KNO3, HNO3 and maybe a trace of (H/K)IO3. The I2/DCM spheres only float and
coalesce very slowly. How to make it coalesce faster?

One or more of :
Heating
Electrostatic field
Centrifuge
Addition/removal of surfactant to reduce energy needed for coalescence.

Also, relative density.

Maybe especially.
Dichloromethane is not much good at floating.
If you've got a solvent with a density below 1 which will do the job I bet it'll float damned fast in an aqueous solution that's dense enough to float
DCM.
