Celite does absolutely nothing to a solution except act as a physical filtration media. It does not have the same mode of action as bentonite or activated charcoal, the main principal to be observed with those two media is ADsorption. These types of media can remove particles that have been totally dissolved in solution.
Celite 545 is meant to be used for depth filtration to remove solid particles that either wont dissolve or cant dissolve in the solution.
