what is the best way for remove AL from the liquid solution that contains Fe, S, Mg,..?
what is the best PH?
This will depend on the oxidation state of the elements. Fe(III) are quite similar to Al(III), but it is easy to find reactions that can seperate Fe(II) from Al(III).
thanks for your guide. in my liquid solution all of the Fe are (II). is it possible to omit AL by adding NaOH (pH=5) without missing concentration of Fe (II)?
It seems the most obvious to increase the pH, but you most also consider the oxidation stage of the other elements. E.g. as pH increases it might be that Fe(II) or Mn(II) could precipate as sulfides if S is in the -II state.
You are right. I have also S in my sample .
in your opinion what should I do ? I want to minimize the concentration of Al in my liquid sample and then do other work.
