Small limited quantities of the inert gas radon can be collected with an 
activated charcoal filter by physical adsorption, so I expect the same 
would be true for the inert gas krypton. However, one would expect that 
this process would not be effective for large quantities of krypton. You 
could do some experiments to measure the saturation level. The collected 
krypton can be measured by external measurement of the filter before and 
after heating it to release the adsorbed gases..
