NEW PAPER: Ion exchange removal of Cu(II), Fe(II), Pb(II) and Zn(II) from acid extracted sewage sludge

Grantham Scholar James Bezzina is first author of a paper that looks at a process where weak acid leaching of sewage sludge would be coupled to ion exchange for heavy metal ion removal.

Highlights:
• MTS9301 is effective at extracting selected metal ions from all tested media.

• Citrate media is effective at hindrance of metal adsorption.

• TP214 can selectively extract copper from high complexing solutions.

• C107E can selectively extract lead from lactate media.
