Pertiwi Andarani

Thank you for your kind reply.

However, my concern is not how the membrane remove the elements, but is it possible to measure the elements ON the surface of CA membrane?

We use the membrane to measure the concentration of Dissolved Metal in a river water. We would like to verify whether the "Total Metal = Dissolved Metal + Particulate (SS) Metals" are correct.

We are still looking for method to measure Particulate/Suspended Metal (*SS = Suspended Solid)
