Much would depend on the precise circumstances. In industrial cases, and some clinical situations, this can be done using pressure swing adsorption. Please see the link.
its used in an oxygen tank because it can help us breathe under water
Yes, a tank of oxygen can be half full. The oxygen would be stuck in said tank meaning no more oxygen can get in unless refueld.
with a nitrogen tank
Usually AIR, which is 21% Oxygen and 79% Nitrogen...BUT!!!! It could have been used for Nitrox, which is elevated Oxygen, If you dont KNOW for sure what is in it, DUMP the gas and refill the cylinder.
The nitrogen moderates combustion and your breathing. Pure oxygen is not good for you if taken too long. The heart beats are driven by nitric oxide. The Sunday times produced a joke cartoon of gentlemen of the road living healthily under the motor way bridge many years ago when it was discovered.. This planet sits on a balance of 79% nitrogen and 20% oxygen. If the oxygen level were to get to 23% we would spontaneously ignite from the sun. Nitrogen is a stable inert gas, yet reactive enough in lightning conditions to oxidise and produce the nitrogen oxide that is a source of subsequent nitrates. At normal pressures nitrogen oxygen ratio is fine but divers have to be careful when ascending too quickly from the depths as "the bends" will occur and nitrogen gets released by diffusion especially at the joints.
I would think so, because there are two of them mixed together. Air in a scuba tank or anywhere else should be heterogeneous. A scuba tank filled with either oxygen or nitrogen would be homogeneous.

Purge solenoid is on the gas tank along with the evap cannister.

when you go diving, you take a pressurized tank of air, air consists of about 79% Nitrogen and 21% Oxygen, at normal pressure (atmospheric pressuer) the partial pressure of Nitrogen is 0.79 Bar and Oxygen 0.21 Bar which is safe. Under high pressures (say 5 Bar which is at a depth of about 40 metres) the partial pressure of each gas increases Nitrogen (0.79x5=3.95Bar) which causes the lungs to absorb the nitrogen at a higher rate which influences the nervous system causing Narcosis (As if you're Drunk) The reason why you can't take a tank of oxygen instead of air is that oxygen becomes toxic at higher partial pressures
with a nitrogen tank
Plants would provide oxygen in a fish tank.
A pressure regulator is required on a nitrogen tank.
