Abstract

EN 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.
