there are two methods either precipitating sulphate or precipitating chloride
the simplest thing is just add silver nitrate
and u will immediately get a curdy white ppt of silver chloride sulfate remains in soln.
the second way is to add barium chloride which will precipitate sulphate as barium sulphate.

Ca2+ or Ba2+ will allow chlorine to be retained in solution and precipitate out the sulfate

use Ba or Ca to precipiatate out one ion before the next. Pay attention to the Ksp values
