Determination of mercury in real samples by atomic spectrometry and stripping voltammetry

Abstract

The mercury detection from real samples of soil using chemically modified electrodes with films based on pyrrole-EDTA monomer was performed and the results were compared to those obtained by Atomic Absorption Spectroscopy, currently used in environmental laboratory analysis. The ligand used for electrode modification is ethylendiaminotetra-N-(3-pyrrole-1-yl)propylacetamide (L). The electrochemical method used for mercury detection was the anodic stripping voltammetry on polyL modified electrodes. The experiments have shown that mercury levels obtained by both methods are comparable.
