Summary:Copper is encountred frequently in the environment, in part because of its relatively high abundance in the earth's crust. Copper is also found due to anthropogenic activities as it is produced at higher volume anually compared to gold and silver and its use as an algal control chemical. The high affinity of Cu2+ ions to poly-4-vinyl pyridine (P4VP) polymer led us to fabricate and electrode containing P4VP polymer anchored into the surface of modified Polyethylene terephthalate (PET) printed electrodes using carbon nanotubes (CNTs) as a charge carrier. The P4VP will preferatially form strong association or “grab” Cu2+ ions in solution, enabling copper identification and quantification.
