recently we are facing a trace heavy metal problem in our project.
We are using an aqueous oxidizing agent which contains a tiny amount of heavy metal ion. In our application, we aim at basically ELIMINATING TOTALLY ALL heavy metal ion in the liquid oxidizer.
example of heavy metal ions are As, Ba, Cd, Cr, Pb, Se...etc
Is there any practical well known approach to achieve this goal(to be as clean and pure as possible)?
Thank you for your advise.
