Hi Sreesailam,
Electrical mobility is the ability of charged particles (such as electrons or protons) to move through a medium in response to an electric field that is pulling them. The separation of ions according to their mobility in gas phase is called Ionic mobility.
When a charged particle in a gas or liquid is acted upon by a uniform electric field, it will be accelerated until it reaches a constant drift velocity according to the formula:

where
is the drift velocity (m/s)
is the magnitude of the applied electric field (V/m)
is the ionic mobility (m2/(V.s)).....
That's the concept of Ionic Mobility.
Best Regards,
