Ion exchange removal of Cu(II), Fe(II), Pb(II) and Zn(II .

A shortage of phosphate rock resources has led to a focus on the use of sewage sludge as a fertiliser. One factor preventing the unlimited application of sewage sludge in agriculture is the heavy metal content. This work looks at a process where weak acid leaching of sewage sludge would be coupled to ion exchange (IX) for heavy metal ion removal.

This study presents the pH performance of six selected IX resins in extracting Cu 2+, Fe 2+, Pb 2+ and Zn 2+ from acetic, lactic and citric acid media simulated weak acid leachate. Acetic acid media displayed limited suppression of metal extraction, whilst lactic and citric acid media rendered MTS9100 ineffective.

You will react each of them with two species that may act as oxidizing agents, water (H 2 O) and hydronium ion (H 3 O +) supplied by hydrochloric acid. Note that the Cu 2+ /Cu couple and the Zn 2+ /Zn couple are also examined in Part B of this experiment. Be prepared to compare the relative reactivities from Part A with your observations from measuring cell potentials in Part B.
