Is it possible to selectively remove iron from a solution? Chris Coon Borden Chemical Kent, WA Chris, You can remove lead by precipitation at a pH of above 8.5. A little Sodium Sulfide will remove any remaining lead to meet limits. Iron can be remove selectively from some solutions, for example, chrome plating solutions are purified using a cation resin. A lot depends on the valence of the iron and the other ions in solution.
