Fast potentiometric analysis of lead in aqueous medium under competitive conditions using an acridono-crown ether neutral ionophore
Lead is a particularly toxic heavy metal that is present above acceptable levels in the water
of many countries. This article describes a quick detection method of lead (II) ions using a
polyvinyl chloride (PVC)-based ion-selective membrane electrode containing an acridono-
crown ether ionophore by potentiometry. The electrochemical cell exhibits a Nernstian
response for lead (II) ions between the concentration range of 10− 4 to 10− 2 M, and can be
used in the pH range of 4–7. The applicability of this sensor was verified by measuring a …

Lead is a particularly toxic heavy metal that is present above acceptable levels in the water of many countries. This article describes a quick detection method of lead(II) ions using a polyvinyl chloride (PVC)-based ion-selective membrane electrode containing an acridono-crown ether ionophore by potentiometry. The electrochemical cell exhibits a Nernstian response for lead(II) ions between the concentration range of 10−4 to 10−2 M, and can be used in the pH range of 4–7. The applicability of this sensor was verified by measuring a multicomponent aqueous sample. Under the given conditions, this electrode is suitable for the selective quantitative analysis of lead(II) ions in the presence of many additional metal ions.
