Abstract

Optimal working parameters for the innovative electrode GCE/AgNPs‐D3 were determined and the selectivity was assessed. The stripping anodic peak current of thallium characterized in linearity over range from 4.9 ⋅ 10−8 to 4.9 ⋅ 10−7 mol ⋅ dm−3, with LOD = 7.16 ppb (3.5 ⋅ 10−8 mol ⋅ dm−3). Furthermore, the new electrode showed more than sevenfold improvement in the thallium current signal compared to the unmodified electrode GCE. High selectivity was achieved using EDTA disodium salt as a complexing agent for other metals. [ABSTRACT FROM AUTHOR]
