Separate sugar from citric acid solution.

Question

If they are in solution, you can do this by evaporation. Look at the boiling point for citric acid and depending on the sugar, you can do that. 
Or, you can do a filtration. I'm assuming that the sugar will remain on top wile citric acid will flow right through the filter.  Sugar is larger in size in comparison to citric acid.

If I dry the water out, I'll end up with sugar and citric acid crystals all mixed. Upon heating (you're talking about boiling points) sugar oxides and citric acid decomposes.

Could you elaborate on filtration? Sugar and acid both pass filter when dissolved.

Can I ask, are we assuming that citric acid and sugar are in same solution?

Add calcium ions to the solution.  Calcium citrate will precipitate and can be separated by decanting or filtration.  The sugar remains in the liquid.  The citric acid can be recovered by treating the calcium citrate with an acid.
