A Novel Approach For In Situ Monitoring Of Zn2+ In Citrus Plants Using Two-Step Square-Wave Anodic Stripping Voltammetry

Abstract

This study presents in situ detection of Zn2+ using a novel two-step square-wave anodic stripping voltammetry (SWASV)-based needle-type microsensor for citrus plant applications. A double-barrel bismuth/platinum (Bi/Pt) microelectrode was fabricated with a solid metal tip (∼110 μm), which was durable enough to penetrate the thick skin of the citrus leaves and sensitive enough to detect ppb changes in Zn2+ concentration using SWASV. The microelectrode tip size was also determined to reduce mass transport limitation and improve limit of detection. Overall, the developed Bi/Pt microelectrode successfully measured Zn2+ concentrations within the vascular bundle of citrus plants.
