how to separate DC and AC with low frequency? here "low frequency", i mean, in 10Hz range. a simple inductor and capacitor seem not the solution.

it may be a silly question, but i really have no idea right now. can anybody give me some hints? thanks in advance.

A series capacitor will pass AC and block DC
A series inductor will pass DC and attenuate AC

I'm not sure if that qualifies as separation. If not you need to refine the question.
