Will increasing the ionic strength of a solution result in an increase
of sulfate ion adsorption in an anion exchange system?

Hi joseph777,

The answer is that it depends on the capacity of the ion exchange
system. These systems have a maximum capacity of exchange per unit. So
if you have more Sulfate ion then capacity, increasing the ionic
strength will not result in increased absorption, because the ion
exchange system is at capacity. If your ion exchange system is below
capacity, increasing the ionic strength of the solution will result in
more absorption, because more ions are available for absorption.

Hope this helps!
