Kurzfassung:
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.
