Elucidation of Cu-AMT Structure by Voltammetric Method

Abstract

The long-term anthropogenic release of metals has increased their distribution and concentration in ecosystems, leading to sustained interest in their behavior and impact. Metals are not biodegradable and are converted from one chemical state to another. Even in low concentrations, heavy metals carry high danger. Therefore, the need for continuous control of trace metals in the environment is increasing. In this technique, the metal to be analyzed is deposited on the electrode surface in the form of metal complexes, and determinations are made using the peak currents obtained by potential scanning in the cathodic or anodic direction. The sensitivity and selectivity of the assay are increased by the choice of the ligand used as the complexing agent. In the study carried out to elucidate the structure of the complex formed by Cu(II) with 5-amino-1,3,4-thiadiazole-2-thiol (AMT), it was estimated that the complex structure could probably be in the ratio of 1:1. In addition, studies have been carried out to determine the stability of the complexes to be formed in various environments since the stability of the complex is related to the species in the solution comprising the medium, its concentration and the pH of the solution.
